Abstract

<p>This study aims to investigate the effect of wearing walking shoes with different center-of-gravity positions on gait in adult males. For this, 19 adult males were asked to wear shoes with three different center-of-gravity positions （toe-, central-, and heel-weighted） and walk on a 9 m-walking path, and the foot clearance, floor reaction force, lower limb joint angle, and lower limb joint moment were calculated. The results revealed that the knee joint moments during the loading response phase were considerably smaller in the heel condition than in the toe and central conditions. The vertical floor reaction force during the loading response phase （the vertical peak 1 of the floor reaction force） was considerably smaller in the central and heel conditions than in the toe condition. The knee joint angle during the initial swing phase and the hip joint angle during the mid-swing phase were considerably smaller in the central condition than in the toe condition. These results suggested that knee and hip flexion should be increased in the toe condition to ensure clearance during the swing phase. Furthermore, the heel rocker function was observed to be stable during the load response phase under heel conditions.</p>
