Purpose: This study aimed to compare running economy across habituated and nonhabituated advanced footwear technology (AFT) in trained long-distance runners. Methods: A total of 16 participants completed up to six 5-minute trials in 1 to 3 pairs of their own habituated shoes and 3 different and standardized AFTs at individual marathon pace. We measured oxygen uptake and carbon dioxide production and expressed running economy as oxygen uptake (in milliliters oxygen per kilogram per minute), oxygen cost of transport (oxygen per kilogram per minute), energetic cost (in watts per kilogram), and energetic cost of transport (in joules per kilogram per kilometer). We used linear mixed-effect models to evaluate differences. Relative shoe weight and shoe mileage (distance worn during running) were covariates. Results: Forty-eight standardized and 29 individual AFT conditions were measured (mileage 117.0 [128.8] km, range 0–522 km; 25 habituated 135.7 [129.2] km, range 20–522 km; 4 nonhabituated 0 [0] km, range 0–0 km). Rating of perceived exertion, blood [La], and respiratory exchange ratio ranged from 9 to 15, 1.11 to 4.54 mmol/L, and 0.76 to 1.01. There was no effect for habituation on energetic cost of transport (thabituation = −.232, P =.409, b = −0.006; 95% CI, −0.058 to 0.046) or other running economy metrics. Neither shoe weight nor shoe mileage had an effect. Conclusions: Our results suggest that habituation to AFTs does not result in greater benefits in the use of AFTs. This means that implementation in training may not be needed, even if we cannot rule out any other possible benefits of habituation at this stage, such as adaptation of the musculoskeletal system.

Aims: Incorrectly fitting footwear (IFF) poses a risk of trauma to at‐risk feet with diabetes. The aim of this systematic review was to summarise and assess the evidence that IFF is a statistically significant cause of ulceration. Methods: We searched PubMed, Scopus, Web of Science and Google Scholar for English‐language peer‐reviewed studies reporting the number or percentage of people with diabetes‐related foot ulceration (DFU) attributed to wearing IFF and included a physical examination of the footwear worn. Two independent reviewers assessed the risk of bias using the Newcastle–Ottawa scale. Results: 4318 results were retrieved excluding duplicates with 45 studies shortlisted. Ten studies met the inclusion criteria with most rated as fair (n = 6) or good (n = 3). There is some evidence that DFU is significantly associated with IFF, but this is limited: only 3 of 10 included studies found a statistically significant percentage of those with DFU were wearing IFF or inappropriate footwear which included fastening, material, type or fit (15.0%–93.3%). Risk of bias in these three studies ranged from 'fair' to 'poor'. IFF definitions were often unreported or heterogeneous. Only one study reported IFF‐related ulcer sites: 70% were at plantar hallux/toes and 10% at plantar metatarsal heads. Conclusions: There is some evidence that IFF is a cause of DFU, but further research is needed, which defines IFF, and methodically records footwear assessment, ulcer location and physical activity. Researchers need to uncover why IFF is worn and if this is due to economic factors, a need for footwear education or other reasons. [ABSTRACT FROM AUTHOR]

Background: This hypothesis introduces pump shoes as a method for the prevention and treatment of varicose veins. Method: An air pump is placed in the shoe, connected to an airbag wrapped around the leg through a hose. With each step, air is pumped into the foot airbag, applying pressure to the leg muscles and superficial veins. This action mimics muscle pumping, helping to push blood back towards the heart. Excess air is released through an outlet hose with an adjustable sphincter, allowing for increased pressure on the leg. Results & Conclusion: These shoes offer a simple mechanism to assist in returning blood from the feet to the heart. They can be beneficial in preventing varicose veins in at-risk individuals or treating those in the early stages of the disease. [ABSTRACT FROM AUTHOR]

Visual search can be guided by biasing one's attention towards features associated with a target. Prior work has shown that high-fidelity, picture-based cues are more beneficial to search than text-based cues. However, typically picture cues provide both detailed form information and color information that is absent from text-based cues. Given that visual resolution deteriorates with eccentricity, it is not clear that high-fidelity form information would benefit guidance to peripheral objects – much of the picture benefit could be due to color information alone. To address this, we conducted a search task with eye-tracking that had four types of cues that comprised a 2 (text/pictorial cue) × 2 (no color/color) design. We hypothesized that color information would be important for efficient search guidance while high-fidelity form information would be important for efficient verification times. In Experiment 1 cues were a colored picture of the target, a gray-scaled picture of the target, a text-based cue that included color (e.g., "blue shoe"), or a text-based cue without color (e.g., "shoe"). Experiment 2 was a replication of Experiment 1, except that the color word in the text-based cue was presented in the precise color that was the dominant color in the target. Our results show that high-fidelity form information is important for efficient verifications times (with color playing less of a role) and color is important for efficient guidance, but form information also benefits guidance. These results suggest that different features of the cue independently contribute to different aspects of the search process. [ABSTRACT FROM AUTHOR]

Eliud Kipchoge's sub-two-hour marathon in 2019 generated both wide-ranging celebration and stern denigration from members of the running community. The latter, motivated by an unexpectedly superior result, turned to stigma rhetoric to protect what they saw as a danger to their sport: the Nike Alphafly. Stigma is an othering strategy that brands its objects as undesirable and threatening to the ideological center of a community. In Kipchoge's case, his shoe was characterized as technological doping, and rhetors used the framework provided by stigma to imbue the shoe with a moral dimension to warn others away from the threat to the running community's egalitarianism. This case demonstrates how sport communities perceive and respond to threats to their essential natures through common rhetorical frameworks. [ABSTRACT FROM AUTHOR]

The most important role of footwear is to ensure safe, functional walking, and foot protection. For the proper functionality of not only the work shoes, the anti-slip behavior of the shoe under various conditions and environments plays an important role in the prevention of slips, trips, falls, and consequent injuries. This article is intended to review the current understanding of the frictional mechanisms between shoe outsoles and various counterfaces that impact the evaluation of outsole slipperiness. Current research focuses on the mechanisms driving outsole friction on different ground surfaces or the definition and description of parameters that influence outsole friction. Subsequently, the review discusses the effect of various surface contaminants on footwear friction. Lastly, challenges and outlooks in the field of footwear outsoles are briefly mentioned.

My aim in this article, simply put, is to put you in the shoes of the Other. It is by definition an impossible exercise, but that is what I am trying to do in any case. Put you in my shoes, and that of another Other, Saima. Our life trajectories are very different but what joins them is our struggle and strife to cross real or metaphorical borders in the hope of overcoming our precarious conditions of existence. In these new lands, we must reconstitute ourselves to fit with norms that do not otherwise recognize our embodied modes of being. I speak of this performative demand to translate ourselves into the dominant language to qualify for recognizability, legitimacy, and intelligibility. A translation that is always susceptible to failure. But I can also make subversive use of my acquired language: I speak it to render you vulnerable to my plea. [ABSTRACT FROM AUTHOR]

The Compass company as one of the local shoe manufacturers in Indonesia faces intense competition, which requires them to continue to innovate and improve product quality in order to achieve competitive advantage. This study aims to determine the effect of innovation and product quality on the competitive advantage of Compass products. The research method used is quantitative method with descriptive-causality research type. Sampling was carried out using non-probability sampling technique saturated sampling type with 100 respondents. Data were analyzed using multiple linear regression analysis. The results showed that product innovation has a significant effect on competitive advantage with a t value of 5.512> t table 1.988, and product quality also has a significant effect on competitive advantage with a t value of 4.510> t table 1.988. Simultaneously, product innovation and product quality have an effect of 60.6% on competitive advantage, while 39.4% is influenced by other variables outside this study. The conclusion of this study is that product innovation and quality play an important role in creating a competitive advantage for Compass products. [ABSTRACT FROM AUTHOR]

Introduction: Adherence to wearing prescribed footwear is paramount in reducing the risk of developing diabetes‐related foot ulcers, but adherence is often lower than optimal. This study aimed to investigate predictors of footwear adherence and variations in adherence and activity in people at risk of diabetes‐related foot ulceration. Methods: Sixty people at high foot ulcer risk were included. We measured the proportion of weight‐bearing acitivity time the prescribed footwear was worn for seven days. Multiple linear regression and analysis of variance were used. Results: Mean overall adherence was 63%. Adherence was lower at home than away from home (59% vs. 74%), while activity was higher at home (2.2 vs. 1.2 h/day). Adherence was similar across activities (61%–63%). No variable predicted the overall adherence. Higher Hba1c predicted lower adherence at home (β = −0.34, p = 0.045, R2 = 11.6%). More daily steps predicted lower adherence away from home (β = −0.30, p = 0.033, R2 = 9.3%). Adherence and activity were highest in mornings (71%, 1.1 h) and afternoons (71%, 1.5 h), and lower in evenings (40%, 0.8 h) and at nights (9%, 0.1 h). Adherence was similar on weekdays and weekend days (63% vs. 60%), but activity was higher on weekdays (3.4 vs. 3.0 h). Conclusion: Adherence levels and predictors thereof differed between adherence at home and away from home, so we suggest to treat them as different concepts. Due to the low explained variance, future studies should focus on other predictors such as psychological variables. [ABSTRACT FROM AUTHOR]

Background: The field of medical grade footwear is dynamic. Originally, a field where individual knowledge, expertise and skills determined the footwear and its outcomes, now becoming a more evidence‐based and data‐driven field with protocols and systems in place to create appropriate footwear. However, scientific evidence concerning medical grade footwear is still limited. Evidently, all stakeholders, from patients to pedorthists to rehabilitation physicians, will profit from a larger evidence‐base in this field. A widely supported research agenda is an essential first step to advance and facilitate new knowledge. Methods: We formed a multidisciplinary team and followed the methodology from Dutch medical societies for the development of a research agenda on medical grade footwear. This consisted of seven steps: (1) inventory of relevant questions with users and professionals; (2) analyses of responses; (3) analyses of existing knowledge and evidence; (4) formulating research questions; (5) prioritising research questions by users and professionals; (6) finalising the research agenda and (7) implementing the research agenda. Results: In phase 1, 109 participants completed a survey, including 50% pedorthists, 6% rehabilitation physicians and 3% users. Participants provided 228 potential research questions. In phases 2–4, these were condensed to 65 research questions. In phase 5, 152 participants prioritised these 65 research questions, including 50% pedorthists, 13% rehabilitation physicians and 9% users. In phase 6, the final research agenda was created, with 26 research questions, categorised based on the International Classification of Functioning Disability and Health 'process description assistive devices'. In phase 7, an implementation meeting was held with over 50 stakeholders (including users and professionals), resulting in seven applications for research projects based on one or more research questions from the research agenda. Conclusions: This research agenda structures and guides knowledge development within the field of medical grade footwear in the Netherlands and elsewhere. We expect that this will help to stimulate the field to tackle the research questions prioritised and with that to advance scientific knowledge in this field. [ABSTRACT FROM AUTHOR]

Background: Diabetic foot is a global threat to public health, as it can lead to infections and amputations and cause significant pain and economic costs for patients. Diabetic foot patients in northern China have more severe local ulcers, worse prognosis, and longer disease duration. Objective: This study assessed the foot risk levels and foot care knowledge and behavior status of people with diabetes with different foot risk levels, and investigated the factors that influence the occurrence of high-risk foot in diabetes. Methods: This cross-sectional survey included 410 hospitalized people with diabetes. Demographic and disease-related data and foot risk stratification status were collected using investigator-designed questionnaires. Foot care knowledge and behavior questionnaires were also used. Results: Among the 410 participants, a total of 367 cases were classified as high-risk feet, among which 135 cases were rated as grade 1, 202 cases grade 2, and 30 cases grade 3. Foot care knowledge surveys revealed low scores in the areas of shoe and sock selection, foot and footwear examination, and management of foot problems. Foot care behavior surveys showed low scores in the areas of foot and footwear examination, management of foot problems, and foot injury risk behavior. One-way ANOVA revealed significant differences in foot care behaviors among patients with different foot risk classifications (p < 0.05), while no significant differences were observed in foot care knowledge scores. Multivariate logistic regression analysis showed that age, history of cerebrovascular disease, and foot care behavior scores were factors influencing the occurrence of high-risk foot in people with diabetes. Conclusion: The results of this study showed a high prevalence of high-risk foot in diabetics; The knowledge and behavior of foot care in diabetics with different foot risk levels were both at a moderately low level; There were differences in foot behavior scores among patients with different foot risk classes, but, counter-intuitively, no significant differences in foot care knowledge. The study found that advanced age, history of cerebrovascular disease, and low foot care behavior scores are risk factors for high-risk foot in diabetes. Therefore, it is necessary to screen patients with diabetes for high-risk feet and implement targeted interventions according to the results. [ABSTRACT FROM AUTHOR]

Magnetic fields from the linear motor, suspended electromagnet, and collector shoe arcing are the three main electromagnetic interference (EMI) sources for the medium–low-speed maglev train interior. Under their collective influence, the field intensity may exceed the standard threshold, consequently affecting the operational reliability of the train system. However, in previous studies, the EMI sources were analyzed separately, and studies regarding the influence of factors such as the motor states and the train body (TB) shielding against arcing EMI were lacking. Therefore, in this paper, all three EMI source are considered, and an EM disturbance source modeling scheme is proposed using the COMSOL software platform. Its effectiveness is demonstrated and the train interior magnetic field is analyzed, primarily with respect to prior simulations and tests. Subsequent analyses enable a comparative assessment of the individual contributions of each EMI source to the overall interference, considering the EMI control standards. The influence of other EMI source parameters, such as different motor states, is analyzed, and the potential for modifying the material composition and structural thickness of the TB is explored to determine the appropriate EMI inhibition strategy.

Background: Plantar fasciitis, a common musculoskeletal disorder, is characterized by inflammation of the plantar fascia, a thick band of tissue that connects the heel bone to the toes. The plantar fascia plays a crucial role in supporting the arch of the foot and absorbing shock during movement. Factors such as excessive physical activity, improper footwear, and biomechanical abnormalities are recognized contributors to the development of plantar fasciitis. However, the prevalence and underlying causes may vary across different demographic groups, necessitating targeted investigations. Objective: This study aims to investigate the prevalence, causes and treatment of plantar fasciitis in young female students (18–30) of a medical college in Pakistan and explore potential associations with high-heel footwear. Methodology: In this study, a cross-sectional survey was carried out, engaging 100 young females from a medical college. Employing a structured questionnaire, we assessed a spectrum of parameters, including heel pain symptoms, footwear habits, and available treatment options. The diagnostic precision of the Windlass test, specific to plantar fasciitis, was incorporated. Rigorous data analysis, utilizing SPSS, centered on discerning associations between the nuances of high-heel wear (considering types and duration) and the reported symptoms. This methodological framework ensures a comprehensive and precise exploration of the prevalence, causes, and treatment of plantar fasciitis in our targeted demographic. Results: All the participants were female, and the total number was 100, of which 66% felt pain in the heel when they wore high heels. Out of this 66%, only 6% are diagnosed with plantar fasciitis. The rest of the 60% have pain in the heel due to different causes such as heel spurs, stress fractures, etc. 2% of people receive treatment with steroid injections, and 12% are treated with ice. Conclusion: We conclude that the prevalence of plantar fasciitis is high in females wearing high heels. This study reveals that an increase in the total duration of wearing high heels with hard soles increases the symptoms of plantar fasciitis. Plantar fasciitis can be prevented by education and applying ergonomics and could be treated by steroids and the ice method, according to medical practitioners. [ABSTRACT FROM AUTHOR]

Introduction: Nearly, a quarter of older adults suffer from frequent foot pain, impacting their quality of life. While proper footwear can alleviate this, design issues often hinder regular use. This study evaluated novel therapeutic footwear, designed for aesthetics and custom fit, to reduce foot pain. We hypothesized that older adults would experience less foot pain and favor the new footwear over their own. Methods: This 12-week crossover randomized controlled trial evaluated the effectiveness of OrthoFeet therapeutic footwear on reducing foot pain in older adults (n = 50, age = 65 ± 5, 18% male) with moderate to severe pain. Participants were assigned to either the AB or BA sequence. In AB, they wore OrthoFeet shoes for 6 weeks and then their own shoes for another 6 weeks; BA followed the reverse order. Pain and function were measured using the Foot Function Index. Acceptability was assessed through a technology acceptance model (TAM) questionnaire. Data collected at baseline, six, and 12 weeks were analyzed using t tests, χ2 tests, and generalized linear model. Results: Compared to participants' own shoes, OrthoFeet shoes significantly reduced foot pain and disability. Notable improvements were observed in "foot pain at its worst," "foot pain at the end of the day," "overall pain score," and "overall Foot Function Index score," all showing statistically significant reductions (p < 0.050). Participants reported high adherence to wearing the OrthoFeet shoes, averaging 8 h per day and 5.8 days per week. TAM scores favored OrthoFeet shoes over participants' own shoes in terms of ease of use, perceived benefit, and intention to recommend. Significant differences were noted in components representing perceived joint pain relief (p < 0.001, χ2 = 21.228) and the intention of use as determined by the likelihood of recommending the shoes to a friend with a similar condition (p < 0.001, χ2 = 29.465). Additionally, a majority of participants valued the appearance of the shoes, with 66% prioritizing shoe appearance and 96% finding the study shoes more stylish than their previous ones. Conclusion: This study underscores the significance of design and custom fit in promoting continuous wear for effective foot pain reduction in older adults. More research is needed on the intervention's long-term impacts. [ABSTRACT FROM AUTHOR]

Background: This study aims to assess the impact of safety footwear (SF) on workers concerning foot-related problems, especially regarding discomfort, foot pain, and skin lesions. Methods: A literature search of PubMed, Embase, Scopus, and Cochrane databases was performed according to PRISMA guidelines. Studies reporting foot-related problems in workers wearing SF were included. Exclusion criteria included non-English papers, reviews, laboratory and animal studies, expert opinions, letters to the editor, and grey literature. The quality assessment was performed using the Newcastle–Ottawa Scale. Descriptive statistic was used to present data. Result: The initial search results yielded 483 articles; 7 articles were included in the review process. Despite the extensive variety of SF, all studies consistently reported symptomatic discomfort and pain. The discomfort factors included heat, sweating, heaviness, and footwear flexibility, with primary issues in the toes, toecaps, or metatarsal–toe crease region. The pain prevalence ranged from 42.3% to 60.8% in various anatomical regions. Irritant Contact Dermatitis was the most common (97.9%) foot dermatosis, but other foot lesions were reported: dry skin (30.2%), calluses (30%), hard nails (28%), corns (27%), and blisters. Conclusions: Current SFs are designed to comply with safety regulations but are influenced by the frequent occurrence of discomfort and foot problems. The literature review identified weaknesses in certain design features. Recommendations have been proposed to improve SF development. These include addressing issues such as the selection of specific types and designs of SF based on task performance and the working environment, footwear weight, and breathable materials for moisture permeation. Considerations should also encompass distinct sizing for an optimal fit, insole application, especially for prolonged standing users, and education programs to prevent foot-related issues.

Purpose: The Nike Vaporfly line of running shoes improves running economy by ∼2.7% to 4.2% at running speeds of 13 to 18 km·h−1. It is unclear whether similar benefits are conferred at slower speeds. Our purpose was to determine the effects of the Nike ZoomX Vaporfly Next% 2 (VFN2) on running economy at 10 and 12 km·h−1 compared with a mass-matched control (CTRL) shoe. Methods: Sixteen runners completed 4 × 5-minute trials at both 10 and 12 km·h−1 on the same day. Each shoe was tested twice at each speed in a counterbalanced, mirrored sequence. Data are displayed as mean (SD). Results: A 2-way repeated-measures analysis of variance showed a significant shoe × speed interaction for oxygen consumption (P =.021). At 12 km·h−1, oxygen consumption (in mL·kg−1·min−1) was lower (−1.4% [1.1%]; P <.001) for VFN2 (35.8 [1.7]) relative to CTRL (36.4 [1.7]). That was greater in magnitude than the differences observed at 10 km·h−1 (−0.9% [1.8%]; P =.065) between VFN2 (29.4 [1.9]) and CTRL (29.6 [1.9]). Conclusions: From these data, it appears that the VFN2 still enhances running economy at 10 and 12 km·h−1; however, these benefits are smaller in magnitude compared with previous research at faster speeds.

Soccer is a sport with a high incidence of injuries. The most common injury occurs when the anterior cruciate ligament of the knee has undergone a sprain, strain, or partial or total rupture. Besides fitness factors (e.g., proprioception, balance and strength capabilities), a principal cause of ACL injuries is sport shoes and playing surfaces. Especially with the emergence of artificial surfaces (rubbers, turfs, concrete, asphalt, red turf), the ACL injuries dramatically increase. The cost of ACL injuries is high both in terms of career termination and in social and economic costs. Thus, it is necessary to understand the impact of sport shoes and playing surfaces on the ACL and how it can be mitigated. The present literature review followed the PRISMA methodology to identify the major biomechanical factors influencing the behavior of surfaces and shoes in relation to the ACL damage. Fifty-eight papers were identified. After reviewing the mechanism of injuries, we identified several distinct factors: type of outsole and mechanical arrangement of the outsoles; shear forces; characteristics of artificial turf surfaces; effect of weather on artificial surface aging and change in mechanical characteristics; outsole/ground interface; and the frictional, tractional and rotational forces in the pathogenesis of ACL injuries in soccer.

Shoe upper materials are often subjected to repeated creasing in use, which affects their shape retention and aesthetic. The crease recovery property of fabrics is an important property that affects its serviceability. Six variants of warp-knitted jacquard spacer fabrics with different jacquard layer structures were selected and the crease recovery angles on six orientation angles were tested for 30 cycles. The relationship between different orientation angles and crease recovery angles was studied and the comprehensive index for evaluating the crease recovery property of fabric was extracted by the grey relation analysis. The effect of the jacquard layer structure and the number of cycles on crease recovery property was analyzed with MATLAB. The results indicated that the crease recovery angles on different orientation angles were significantly different, and the comprehensive index could evaluate the crease recovery property more reasonably. The influence of the 3-needle underlap and the chain underlap on the crease recovery property was the most significant, and the influence of the 3-needle underlap was greater than that of the chain underlap. Base on solid structure, reducing the proportion of mesh structure or adding semi-transparent structure could improve the crease recovery property. The change rule of crease recovery angles with the number of cycles could be elucidated by the exponential function. [ABSTRACT FROM AUTHOR]

The pose disturbance of the guide shoe under complex working conditions can lead to collision, impact, and wear failure between the guide shoe and the pin row. To explore the damage law of pose disturbance on the guiding shoe, a rigid‐flexible coupling dynamic model of the walking mechanism considering the contact gap between the guiding shoe and the pin row was constructed. The contact characteristics of the guiding shoe under different poses were analyzed. The results indicate that the swing around the x‐axis has the most significant impact on the guiding shoe, with stress concentration primarily occurring near the corner of the trench. The posture of swinging solely around the y‐axis weakens the supporting effect of the guide shoe, resulting in stress concentration on the end face of the left side face. Swinging around the z‐axis results in stress concentrations on the upper faces of the shoe. Research shows that the angular velocity of the guiding shoe around the x‐axis and z‐axis is highly sensitive to variations in traction speed. In addition, an increase in lateral force weakens the support effect of the guiding shoe, resulting in elevated contact force on the lower side of the guiding shoe and increased y‐direction load on the walking wheel. The research results provide a reference for exploring the influence of walking unit postures on the failure of the guiding shoe and for improving shearer traction reliability.

Scholars have only paid limited attention to petite feet as a US fashion and as a cross‐cultural beauty ideal. Framed as a visual metaphor of Chinese alterity, traditionalism and patriarchal oppression, footbinding served as a crucial terrain in which the USA asserted its supremacy through a racialised discourse of difference at the turn of the twentieth century. Through a comparative lens, this article spotlights powerful details about shared ideologies of women's bodies in the USA and China. By tracing how women's feet were discussed in newspaper and magazine coverage of US small foot fashion and foot contests, and locating these narratives in a global context, it uncovers the ways in which the discourse of modernity, ideology of white superiority and imperialism naturalised Western women's foot beauty norm as an aesthetic ideal, which obscured the convergences of feminine beauty standards in different parts of the world. Ironically, this racialised global hierarchy of beauty under the guise of modernity tapped into a traditional form of femininity and upset efforts to reflect on the limits of white women's agency both in a traditional patriarchal culture and in a modernising US society, which ultimately constrained possibilities of local and global transformations.

Background: Child footwear, both in pathologies and in normal situations, can affect the foot in various ways depending on its characteristics. Below, some features of child footwear are described, and how they can influence the foot, including suitable size, shape and design, flexibility, and transpirable material; inadequate footwear includes situations with flat foot, equine foot, and hammer toes. It is important to highlight that each child is unique and may have different footwear needs. In case of specific pathologies or concerns, it is recommended to consult a specialist in podology or foot medicine for personalized assessment and recommendations. Methods: The present systematic review was conducted in accordance with the guidelines outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Results: Children's footwear must adapt to all stages of children's growth, starting from when they begin to walk, to promote the correct evolution of their musculoskeletal system. For up to six months, they do not need to wear shoes; socks and similar clothing are enough to warm your feet like a second skin. The flexibility of respectful footwear is essential between six months and three or four years. From that age onwards, the soles can be somewhat thicker, and the buttress can have a certain firmness, but the shoes should remain flexible. Conclusions: Eco-friendly footwear, which typically comes from small businesses and factories, is sometimes described as "ergonomic footwear". However, there is some reluctance towards this term. When choosing this type of footwear for children, it is important to not just look at the label; rather, one should verify that it meets all the necessary characteristics to be considered respectful.

The goal of this study was to use the finite element (FE) method to compare and study the differences between bionic shoes (BS) and normal shoes (NS) forefoot strike patterns when running. In addition, we separated the forefoot area when forefoot running as a way to create a small and independent area of instability. An adult male of Chinese descent was recruited for this investigation (age: 26 years old; body height: 185 cm; body mass: 82 kg) (forefoot strike patterns). We analyzed forefoot running under two different conditions through FE analysis, and used bone stress distribution feature classification and recognition for further analysis. The metatarsal stress values in forefoot strike patterns with BS were less than with NS. Additionally, the bone stress classification of features and the recognition accuracy rate of metatarsal (MT) 2, MT3 and MT5 were higher than other foot bones in the first 5%, 10%, 20% and 50% of nodes. BS forefoot running helped reduce the probability of occurrence of metatarsal stress fractures. In addition, the findings further revealed that BS may have important implications for the prevention of hallux valgus, which may be more effective in adolescent children. Finally, this study presents a post-processing method for FE results, which is of great significance for further understanding and exploration of FE results. [ABSTRACT FROM AUTHOR]

Introduction: Minimalist shoes (MS) are beneficial for foot health. The foot is a part of the posterior chain. It is suggested that interventions on the plantar foot sole also affect the upper segments of the body. This study aimed to investigate the local and remote effects along the posterior chain of four weeks of MS walking in recreationally active young adults. Methods: 28 healthy participants (15 female, 13 male; 25.3 ± 5.3 years; 70.2 ± 11.9 kg; 175.0 ± 7.8 cm) were randomly assigned to a control- or intervention group. The intervention group undertook a four-week incremental MS walking program, which included 3,000 steps/day in the first week, increasing to 5,000 steps/day for the remaining three weeks. The control group walked in their preferred shoe (no MS). We assessed the following parameters in a laboratory at baseline [M1], after the four-week intervention [M2], and after a four-week wash-out period [M3]: Foot parameters (i.e., Foot Posture Index-6, Arch Rigidity Index), static single-leg stance balance, foot-, ankle-, and posterior chain range of motion, and muscle strength of the posterior chain. We fitted multiple hierarchically built mixed models to the data. Results: In the MS group, the Foot Posture Index (b = -3.72, t(51) = -6.05, p <.001, [-4.94, 2.51]) and balance (b = -17.96, t(49) = -2.56, p =.01, [-31.54, 4.37]) significantly improved from M1 to M2, but not all other parameters (all p >.05). The improvements remained at M3 (Foot Posture Index: b = -1.71, t(51) = -2.73, p =.009, [-4,94,0.48]; balance: b = -15.97, t(49) = -2.25, p =.03, [-29.72, 2.21]). Discussion: Walking in MS for four weeks might be advantageous for foot health of recreationally active young adults but no chronic remote effects should be expected. [ABSTRACT FROM AUTHOR]

Minimalist walking shoes have been shown to improve foot muscle size and strength in active adults, but not in our previous study involving children, which could relate to the more structured footwear used in our study. Hence, this study examined the effects of true minimalists on intrinsic foot muscle size and strength, foot arch integrity, and physical function among primary school children. After a baseline assessment, 30 primary school students aged between 9 and 12 were given a pair of minimalist shoes (minimalist index = 92%) as their regular school shoes for two school terms, followed by a re-assessment. Seventeen of the 30 participants in the minimalist group completed the study. Compared to the control group, the minimalist group showed significantly increased cross-sectional area of abductor hallucis (p = 0.047, Cohen's d = 0.57) and flexor digitorum brevis (p = 0.037, Cohen's d = 0.80), increased strength of the hallux (p = 0.015, Cohen's d = 0.76) and lesser toes (p = 0.014, Cohen's d = 0.66), greater arch height (p = 0.020, Cohen's d = 0.52) and standing long jump distance (p = 0.001, Cohen's d = 9.79). The control group exhibited improved standing long jump performance only (p = 0.020, Cohen's d = 10.70). Minimalist shoes worn daily to school promote intrinsic foot muscle size and strength, and improve foot arch integrity among primary school students. [ABSTRACT FROM AUTHOR]

With the global rise in the prevalence of diabetes, diabetic patients need innovative footwear designs to reduce the risk of foot ulcers. This study examined the mechanical properties of diabetic shoe midsoles featuring auxetic lattice structures. Through the construction of finite element models and simulation, this research compared the biomechanical parameter differences in the plantar regions of the metatarsal head, midfoot, and hindfoot when wearing two types of auxetic midsoles with internal angles of 60° and 75° and a non-auxetic midsole with an internal angle of 90° under both walking and running conditions. Compared to the non-auxetic midsole, the auxetic midsoles significantly reduced the peak plantar pressure and optimized the pressure distribution across various plantar regions. Notably, the auxetic 60° midsole reduced the peak plantar pressure by 19.68–55.25% and 16.19–54.39% compared to the non-auxetic 90° midsole during walking and running, respectively. This study also verified that the auxetic midsoles exhibited greater adaptability and compliance to the plantar foot shape, contributing to reductions in plantar pressure in comparisons of deformation values and plantar contact areas across the different midsoles. Auxetic midsoles manufactured using 3D printing technology have significant potential to prevent diabetic foot ulcers and maintain human foot health. This research integrates insights and techniques from materials science and ergonomics, offering a new direction for footwear design. [ABSTRACT FROM AUTHOR]

Using a curved carbon-fiber plate (CFP) in running shoes may offer notable performance benefit over flat plates, yet there is a lack of research exploring the influence of CFP geometry on internal foot loading during running. The objective of this study was to investigate the effects of CFP mechanical characteristics on forefoot biomechanics in terms of plantar pressure, bone stress distribution, and contact force transmission during a simulated impact peak moment in forefoot strike running. We employed a finite element model of the foot-shoe system, wherein various CFP configurations, including three stiffnesses (stiff, stiffer, and stiffest) and two shapes (flat plate (FCFP) and curved plate (CCFP)), were integrated into the shoe sole. Comparing the shoes with no CFP (NCFP) to those with CFP, we consistently observed a reduction in peak forefoot plantar pressure with increasing CFP stiffness. This decrease in pressure was even more notable in a CCFP demonstrating a further reduction in peak pressure ranging from 5.51 to 12.62%, compared to FCFP models. Both FCFP and CCFP designs had a negligible impact on reducing the maximum stress experienced by the 2nd and 3rd metatarsals. However, they greatly influenced the stress distribution in other metatarsal bones. These CFP designs seem to optimize the load transfer pathway, enabling a more uniform force transmission by mainly reducing contact force on the medial columns (the first three rays, measuring 0.333 times body weight for FCFP and 0.335 for CCFP in stiffest condition, compared to 0.373 in NCFP). We concluded that employing a curved CFP in running shoes could be more beneficial from an injury prevention perspective by inducing less peak pressure under the metatarsal heads while not worsening their stress state compared to flat plates.

Heart rate variability (HRV) is a frequently used indicator of autonomic responses to various stimuli in horses. This study aimed to investigate HRV variables in horses undergoing cold (n = 25) or hot (n = 26) shoeing. Multiple HRV variables were measured and compared between horses undergoing cold and hot shoeing, including the time domain, frequency domain, and nonlinear variables pre-shoeing, during shoeing, and at 30-minute intervals for 120 minutes post-shoeing. The shoeing method interacted with time to change the HRV variables standard deviation of RR intervals (SDNN), root mean square of successive RR interval differences (RMSSD), very-low-frequency band, low-frequency band (LF), the LF to high-frequency band ratio, respiratory rate, total power, standard deviation perpendicular to the line of identity (SD1), and standard deviation along the line of identity (SD2). SDNN, RMSSD, and total power only increased 30 minutes after hot shoeing (all p < 0.05). Triangular interpolation of normal-to-normal intervals (TINN) and the HRV triangular index increased during and up to 120 minutes after hot shoeing (p < 0.05–0.001). TINN increased only during cold shoeing (p < 0.05). LF increased 30 and 60 minutes after hot shoeing (both p < 0.05). SD1 and SD2 also increased 30 minutes after hot shoeing (both p < 0.05). SDNN, TINN, HRV triangular index, LF, total power, and SD2 were higher in hot-shoed than cold-shoed horses throughout the 120 minutes post-shoeing. Differences in HRV were found, indicating increased sympathovagal activity in hot shoed horses compared to cold shoed horses. [ABSTRACT FROM AUTHOR]

Soccer is a sport with a high incidence of injuries. The most common injury occurs when the anterior cruciate ligament of the knee has undergone a sprain, strain, or partial or total rupture. Besides fitness factors (e.g., proprioception, balance and strength capabilities), a principal cause of ACL injuries is sport shoes and playing surfaces. Especially with the emergence of artificial surfaces (rubbers, turfs, concrete, asphalt, red turf), the ACL injuries dramatically increase. The cost of ACL injuries is high both in terms of career termination and in social and economic costs. Thus, it is necessary to understand the impact of sport shoes and playing surfaces on the ACL and how it can be mitigated. The present literature review followed the PRISMA methodology to identify the major biomechanical factors influencing the behavior of surfaces and shoes in relation to the ACL damage. Fifty-eight papers were identified. After reviewing the mechanism of injuries, we identified several distinct factors: type of outsole and mechanical arrangement of the outsoles; shear forces; characteristics of artificial turf surfaces; effect of weather on artificial surface aging and change in mechanical characteristics; outsole/ground interface; and the frictional, tractional and rotational forces in the pathogenesis of ACL injuries in soccer.

Lateral ankle sprains are the most common injuries in indoor and court sports, with ankle inversion being a primary injury driver. Stabilising the ankle during multidirectional changes is crucial for injury prevention. Conversely, increased shoe stiffness has been hypothesised to influence the magnitude of ankle inversion and may raise the risk for ankle injuries. Therefore, the purpose of this study was to investigate the influence of shoe longitudinal bending stiffness on ankle biomechanics during indoor and court sport-specific cutting movements. Biomechanical data from 19 participants were collected using a motion capture system and force plate. A jump-cut protocol with two different cutting directions after landing was performed in indoor shoes with and without carbon plate inserts of varying stiffness. Ankle kinematics and kinetics were analysed with statistical parametric mapping and repeated measures analysis of variance. A significant increase in ankle inversion during the 180° cut and a reduction in forefoot inversion (foot torsion) for stiffer footwear conditions during both the 45° and 180° cut were observed. While dorsiflexion moments differed during the last 10% of ground contact, ankle inversion moments did not significantly diverge between shoe conditions. Furthermore, a noteworthy correlation between footwear longitudinal bending stiffness and torsional stiffness was identified. In conclusion, increased bending stiffness significantly affected ankle and foot kinematics. The ankle compensated for restricted mobility and higher demands during high-degree jump-cuts, while foot torsion played a more prominent role in low-degree cuts. The heightened ankle inversion during high-degree cuts may induce an elevated risk for lateral ankle sprains. Further longitudinal studies are necessary to comprehensively understand injury incidence and the role of shoe stiffness in injury prevention. [ABSTRACT FROM AUTHOR]

Footwear has the potential to reduce soft‐tissue vibrations (STV) but responses are highly subject‐specific. Recent evidence shows that compressive garments minimizing STV have a beneficial effect on neuromuscular (NM) fatigue. The aim was to determine whether an individualized midsole hardness can minimize STV and NM fatigue during a half marathon. Twenty experienced runners were recruited for three visits: a familiarization session including the identification of midsole minimizing and maximizing STV amplitude (MIN and MAX, respectively), and two half marathon sessions at 95% of speed at the second ventilatory threshold. STV of the gastrocnemius medialis (GM) muscle, running kinetics, foot strike pattern, rating perceived exhaustion (RPE), and midsole liking were recorded every 3 km. NM fatigue was assessed on plantar flexors (PF) before (PRE) and after (POST) the half marathon. At POST, PF central and peripheral alterations and changes in contact time, step frequency, STV median frequency, and impact force frequency as well as foot strike pattern were found in both MIN and MAX. No significant differences in damping, STV main frequency, flight time, duty factor, and loading rate were observed between conditions whatever the time period. During the half marathon, STV amplitude of GM significantly increased over time for the MAX condition (+13.3%) only. Differences between MIN and MAX were identified for RPE and midsole liking. It could be hypothesized that, while significant, the effect of midsole hardness on STV is too low to substantially affect NM fatigue. [ABSTRACT FROM AUTHOR]

Background: Little is known about factors that influence footwear selection by field hockey players. Methods: An online survey was used to collect data on participant demographics and physical characteristics, factors influencing footwear selection, perceptions regarding footwear design features on injury and performance, and experiences regarding usability. Nominal and ordinal data were described as absolute frequencies and relative frequencies. Free text responses were analysed using content analysis. Sex‐related differences in quantitative and qualitative data were explored. Results: A total of 401 hockey players completed the survey. Participants reported that fit, comfort, support, and cushioning were the most important factors when selecting hockey footwear. Most hockey players believed that stud design could influence athletic performance (65%) and injury risk (63%) but reported having no preference on outsole design or stud shape. Most participants (63%) used hockey‐specific footwear, but 46% of female hockey players did not, with 40% using trail running footwear instead. Qualitative analysis revealed that hockey players, particularly female participants, encounter difficulties finding properly fitting footwear. They desire more options for wide or narrow feet and face challenges in accessing suitable hockey shoes due to limited choices and availability. Conclusions: With over a third of field hockey players not using hockey‐specific footwear, future research should attempt to understand the reasons and assess the impact of different footwear features on comfort, performance, injury risk, and usability.

Background: The type of footwear worn by military personnel and others could increase the risk of overuse injuries. Objectives: This study aimed to compare muscular activity during running with new and used military boots and running footwear in healthy individuals. Methods: Thirty healthy males were given a new pair of running footwear (n = 15) and thermoplastic polyurethane military boots (n = 15). Participants in each group were asked to wear these shoes for 6 months. Electromyographic activity of the dominant limb muscles was recorded during running at a speed of 3.3 m/s before and after 6 months. Results: The results indicated significant differences in muscle activity based on the type of footwear worn during various phases of running. Specifically, muscles such as the tibialis anterior, vastus lateralis, rectus femoris, biceps femoris, and semitendinosus showed varied activity during phases such as loading, mid-stance, and push-off. Additionally, there were significant effects of time on certain muscles, including the tibialis anterior and gastrocnemius medialis during the push-off phase. Interactions between footwear type and time were observed for the semitendinosus and gluteus medius during the loading phase, and the gastrocnemius medialis during the push-off phase. Conclusions: The results of this study indicate a decrease in muscle activity for most lower limb muscles in the military boots group compared to the running footwear group during the stance phase of running. The magnitude of gastrocnemius medialis activity increased in the military boots group (but not in the running footwear group) from pre-test to post-test during the push-off phase.

Background: Physiological changes in the foot may be influenced by external factors such as shoe types or demographic parameters, leading to podiatric conditions in adulthood. The aim of this study was to assess the changes in morphological measurements of the feet of boys and girls during childhood and adolescence. Methods: A total of 1678 Ecuadorian children aged 8 to 17 years participated in the study. The length, width, and height of the foot were analyzed using a 3D scanner to obtain the arch height ratio for the diagnosis of pediatric flat foot. Results: Statistical differences were observed for lengths, widths, and perimeters of the foot in boys aged 5 to 15–16 years and girls aged 5 to 12–13 years. Differences in the height of the navicular bone were found in all age groups, with changes from 2.8 to 4.1% in boys and from 1.3 to 1.5% in girls. The greatest differences between boys and girls of the same age were found at 14 years old onwards. The highest prevalence of flat foot was found in 8-year-old girls (64.9%) and in 12-year-old boys (82.5%). Conclusions: The feet of Ecuadorian children develop progressively during childhood and adolescence. Boys presented with longer and wider feet than girls of the same age. The highest prevalence of flat foot was found in 12-year-old boys and 8-year-old girls. [ABSTRACT FROM AUTHOR]

In order to explore the correlation between the mesh structure design, fabric pore characteristics and the permeability and moisture permeability of the warp-knitted jacquard shoe upper materials, six shoe material samples with different structures were prepared according to the specific design diagram of the fabric. The pore characteristics of the fabric were described from the surface porosity, volume density and average pore diameter, and the influence on the permeability and moisture permeability of the shoe material was compared and analyzed. The results show that the increase of the proportion of thick tissue in the design will reduce the surface porosity of the fabric and increase the volume density, which will reduce the permeability and moisture permeability of the shoe material. The increase of the proportion of mesh structure will increase the surface porosity and decrease the bulk density of the fabric, thus enhancing its air permeability and moisture permeability. The permeability and moisture permeability of shoes with mesh structure design is significantly better than that without mesh structure design under the same fabric thickness, but the permeability and moisture permeability of shoes with larger average pore size under the same mesh proportion design is better.

To prevent frostbite in cold environments, proper dimensions and materials for different parts of shoes along with the optimal design of shoe geometry were investigated. Furthermore, the optimal geometry of shoes was computed using an optimization algorithm to provide maximum thermal protection for the foot while having the lowest weight. The results showed that the length of the shoe sole and the thickness of the sock are the most effective parameters in foot protection against frostbite. Using thicker socks, which only increased the weight by roughly 11%, enhanced the minimum foot temperature by more than 2.3 times. Optimal design of shoe geometry is used to prevent frostbite in cold environments. A model of a biothermal nonlinear model is developed for the barefoot. Length of the shoe sole and the thickness of the sock are the most effective parameters in protecting the foot against frostbite. For the selected weather conditions, the toes are most likely to have frostbite. The best shoe for the selected weather conditions is the shoe that has the highest amount of thermal insulation in the toe area. [ABSTRACT FROM AUTHOR]

BACKGROUND: Shoes upper has been shown to affect the shoe microclimate (temperature and humidity). However, the existing data on the correlation between the microclimate inside footwear and the body's physical factors is still quite limited. OBJECTIVE: This study examined whether shoes air permeability would influence foot microclimate and spatial characteristics of lower limb and body. METHODS: Twelve recreational male habitual runners were instructed to finish an 80 min experimental protocol, wearing two running shoes with different air permeability. RESULTS: Participants wearing CLOSED upper structure shoe exhibited higher in-shoe temperature and relative humidity. Although there was no significant difference, shank temperature and metabolism in OPEN upper structure shoes were lower. CONCLUSIONS: This indicates that the air permeability of shoes can modify the microclimate of the feet, potentially affecting the lower limb temperature. This study provides relevant information for the design and evaluation of footwear. [ABSTRACT FROM AUTHOR]

Abstract Introduction Adherence to wearing prescribed footwear is paramount in reducing the risk of developing diabetes‐related foot ulcers, but adherence is often lower than optimal. This study aimed to investigate predictors of footwear adherence and variations in adherence and activity in people at risk of diabetes‐related foot ulceration. Methods Sixty people at high foot ulcer risk were included. We measured the proportion of weight‐bearing acitivity time the prescribed footwear was worn for seven days. Multiple linear regression and analysis of variance were used. Results Mean overall adherence was 63%. Adherence was lower at home than away from home (59% vs. 74%), while activity was higher at home (2.2 vs. 1.2 h/day). Adherence was similar across activities (61%–63%). No variable predicted the overall adherence. Higher Hba1c predicted lower adherence at home (β = −0.34, p = 0.045, R2 = 11.6%). More daily steps predicted lower adherence away from home (β = −0.30, p = 0.033, R2 = 9.3%). Adherence and activity were highest in mornings (71%, 1.1 h) and afternoons (71%, 1.5 h), and lower in evenings (40%, 0.8 h) and at nights (9%, 0.1 h). Adherence was similar on weekdays and weekend days (63% vs. 60%), but activity was higher on weekdays (3.4 vs. 3.0 h). Conclusion Adherence levels and predictors thereof differed between adherence at home and away from home, so we suggest to treat them as different concepts. Due to the low explained variance, future studies should focus on other predictors such as psychological variables.

Context: Limited evidence exists to demonstrate the effect of extrinsic factors, such as footwear worn or the testing environment, on performance of the modified balance error scoring system (mBESS) in the middle school age (10–14 y) population. Therefore, the purpose of our study was to investigate the effect of footwear types and testing environments on performance of the mBESS by middle school athletes. Design: Cross-sectional. Methods: In total, 2667 middle school athletes (55.9% boys and 44.1% girls; age = 12.3 [0.94] y) were administered the mBESS while wearing their self-selected footwear (barefoot, cleats, or shoes) either indoors (basketball court) or outdoors (football field or track). The number of errors committed (range = 0–10) during the double-leg, single-leg, and tandem stances of the mBESS were summed to calculate a total score (range = 0–30). Kruskal–Wallis tests were used to assess for differences among the footwear groups for each mBESS stance and the total score. Mann–Whitney U tests with calculated nonparametric effect sizes (r) were used to assess for differences between the footwear groups and testing environments when appropriate. Results: There were significant differences for the number of committed errors among the footwear groups in the single-leg (P <.001) and tandem (P <.001) stances of the mBESS and mBESS total scores (P <.001). Significantly fewer errors (better) were committed while wearing shoes compared with other footwear in the single-leg and tandem stances of the mBESS (Ps ≤.032, r =.07–.13). Participants assessed indoors committed significantly fewer errors than those assessed outdoors in each stance of the mBESS (Ps ≤.022, r =.04–.14). Lower (better) mBESS total scores were observed for participants while wearing shoes (Ps ≤.002, r =.10–.15) or assessed indoors (P =.001, r =.14). Conclusions: Although our data suggest that the type of footwear worn and the testing environment have a significant effect on mBESS scores of middle school athletes, the magnitudes of these differences are negligible.
