Abstract

PURPOSE: This study examined the ability of experimental socks combined with a functional insole to reduce plantar foot pressure in healthy subjects. METHODS: The study enrolled 15 subjects. An in-shoe measurement device was used to measure the peak plantar pressure while walking. The peak forefoot, midfoot, and hindfoot plantar pressure data were collected under two conditions: the subjects were wearing their own socks and while they were wearing the experimental socks. The paired t-test was used to determine the differences in peak plantar pressure between the two conditions at all three positions. RESULTS: Wearing the experimental socks resulted in a significantly higher peak plantar pressure in the medial forefoot and midfoot areas than wearing one's own socks (p<.05), and also in significantly lower peak plantar pressure in the medial and lateral hindfoot (p<.05). However, there were no significant differences of peak plantar pressure between experimental and own socks in middle and lateral forefoot (p>.05). CONCLUSION: The experimental socks combined with a functional insole decreased plantar pressure in the hindfoot and supported the medial longitudinal arch. However, it is necessary to change the design and material of the forefoot area in the functional insole to prevent foot ulcer at that location in people with diabetes mellitus.
