The purpose of this study was to investigate the kinematic and kinetic characteristics of intentionally foot inversion wearing high-heeled shoes during stance phase. The study included 9 healthy female students. Prior to participation, each subject was given a detailed description of the purpose and procedures used in the study, and informed written consent was obtained. Shoes with a heel height of 60 mm that were representative of the heel heights available on the market were worn by the study participants. The subjects walked at a comfortable speed. The movement of 2 different walks was analyzed: a usual heel walking (UHW) and an inversion walking (IHW) in which the heel bone was intentionally supinated during the walk. A motion analyzing system (VICON Nexus) was using for analyzing the kinematic and kinetic. Data were recorded throughout the right stance phase of the walking cycle. We defined the stance phase of the walking cycle as the ‘reaction phase’, and the latter phase was the ‘recovery phase’ from an ankle joint angle. Statistical analysis was performed using paired t tests. The result showed that IHW of inversion moment of ankle during recovery phase was significantly increased compared with that of UHW. The lateral force of a force plate (Fx) was significantly deviated to the right according to the moved motion of inversion.
