The purpose of this study was to evaluate the change in three-dimensional (3D) ankle joint kinematics on the arch pad. Ten male subjects performed running trials on treadmill, and ten motion capture system were used to record a position data of the reflected markers on the lower limb. Two conditions (no support and support: arch pad) were compared with the joint angles which were analyzed by the Cardan method. As a result, ankle joint eversion angles with support shoe (-6.5°±2.5°) were significantly lower than that with no support shoe (-10.2°±3.2°) (p<0.01). Nevertheless, differences in ankle joint dorsiflexion and abduction angles were not significantly different between support (20.1°±3.1°, -2.5°±1.9°) and no support shoe (20.4°±3.4°, -2.4°±2.1°) (p>0.25, p>0.11). Shoes with medial arch support or using special shoe inserts may help correct one’s running form by reducing pronation and may reduce risk of running injury.
