The purpose of this study was to investigate the effect of different foot progression angle of the foot at walking. Participants were required to walk three conditions, inward (IN), outward (OUT), control(CON). The condition was defined by foot progression angle at walking. Subjects were instructed to inward or outward at foot progression angle in IN and OUT conditions. In CON, Subjects walked self-selected foot progression angle. It is finding that changing foot progression angle changes frontal foot angle and ankle joint moment. Thus, for changing rearfoot angle and reducing ankle joint muscle load, it may be effective to change foot progression angle.
