There is a lack of scientific evidence about the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The clinical manifestations are not thoroughly understood; classically, the virus manifests itself at the pulmonary level but can manifest at other levels. To the best of our knowledge, systematic reviews and non-systematic reviews about COVID-19 symptoms in the feet have not been published. The aim of this review of reviews was to analyze and synthesize the published reviews on manifestations of COVID-19 at the foot level. Methods: a review of reviews was conducted; the eligibility criteria included studies published in English or Spanish, involving children and adults with COVID-19, and reporting foot manifestations. PubMed, SciELO, Science Direct, Cochrane Database of Systematic Review, and Google Scholar were analyzed. Two authors independently performed the screening and quality assessment of the studies with AMSTAR 1, and finally, nine reviews were analyzed (one systematic and eight narratives studies). The main clinical manifestations at the foot level in patients with COVID-19 were vascular (edema, exanthems, chilblains, ischemia, and distal necrosis), dermatological (vesicular, maculopapular, papulosquamous, urticarial skin breakouts, and recurrent herpes), and neurological (muscular weakness in lower limbs, paresis, areflexias, ataxia, and difficulty walking). Erythema pernio or “COVID toes” was shown as the most characteristic lesion of this disease, especially in asymptomatic children and young people, so this typical manifestation may be considered important in patients who are positive for COVID-19. This finding does not allow for strong conclusions due to the scarce literature and methodological quality in this regard. Future studies are necessary

Background and aims The regular practice of physical activity to improve people´s physical condition such as running or jogging,can damage the lower limb in 79% of the people who practice it.The aim of this study was to determine if foot posture and gait can be modified after 45 minutes of running. Method The sample consisted in 116 healthy adults (92 men and 24 women) with non-pathological feet. The mean age of the participants was 28,31 ± 6,01 years, BMI of 23.45 ± 1.96 kg/m2 and training hours per week of 11.02 ± 4.22. Outcome measures were collected at baseline and after 45 minutes of running at an average speed of 12 km/h, and included the Foot Posture Index (FPI) and a pedobarography analysis with the system Biofoot(IBV, Valencia(Spain). Results The results show foot posture can be modified after 45 minutes of running. The FPI changed from 6,14 ± 2,61 to 4,86 ± 2,65. Furthermore, maximum pressure peak was reduced in the forefoot and increased in the midfoot..The pedobarometric measurement in the heel contact was reduced in the internal area of the foot.The average of maximum pressure was reduced in the internal area and in the forefoot. Conclusion The findings suggest that,after running, pronated foot tends to change its posture into a neutral position, and a decrease in maximum pressure forces in the forefoot and in the area internal the foot is presented.
