[Purpose] The purpose of this study was to compare the effects of heel-height changes on the low joint angles of the lower extremities of women in their 20s during gait. [Subjects and Methods] Qualisys Track Manager Software ver. 2.8 (Qualisys, Sweden) was used to perform measurements on 14 female university students in their 20s. To measure movements, the subjects were asked to walk while wearing high-heeled shoes and reflective stickers on their hip joints, knee joints, and ankle joints, the changes in joint angles were measured at heel strike, foot flat, and toe off. [Results] Analysis of the amount of change according to heel height changes during gait showed that the angle of the hip joints was reduced with an increase in heel-height. Although the changes were not significant, the angle of the knee joints was reduced during heel strike, foot flat, and midstance, and it was increased during toe off. In contrast, the angle of the ankle joints was increased by a significant amount during heel strike, foot flat, midstance, and toe off. [Conclusions] During gait with high heels, the movements of the lower extremities of women in their 20s were reduced significantly with an increase in heel height. Therefore, it is concluded that the restrictions on gait can only be reduced by wearing low-heeled shoes.
