ABSTRACT

PURPOSE: This study examined the kinematic differences in the ankle joint range of motion (ROM) during gait between sneakers and sandals in healthy young adults. METHODS: Thirty university students aged 20−29 years (18 males and 12 females) participated in this cross-sectional study. The participants performed a 10-meter walk test under two footwear conditions: sneakers and sandals. The order of the conditions was randomized to minimize the potential order effects. The ankle joint kinematics were measured using a twin-axis electronic goniometer attached to the lower leg to record dorsiflexion and plantarflexion angles during walking. The total ankle ROM, peak dorsiflexion, peak plantarflexion, and walking time under the two footwear conditions were compared. RESULTS: Walking in sandals resulted in a significantly reduced the total ankle ROM (6.45 ± 2.27°) than walking in sneakers (7.90 ± 2.06°, p < .05). Specifically, both peak dorsiflexion (3.45 ± 3.48° vs. 7.24 ± 4.28°) and peak plantarflexion angles (−21.08 ± 6.02° vs. −28.02 ± 5.34°) were significantly lower under the sandal condition than under the sneaker condition. In addition, the time required to complete the 10-meter walk test was significantly longer when participants wore sandals (8.44 ± .92s) compared with sneakers (8.09 ± .76s, p < .05). CONCLUSION: These findings suggest that the structural characteristics of sandals may limit the dynamic ankle motion during gait. This restriction may help decrease walking efficiency and potentially influence gait stability in young adults.
