Abstract: Objective: In order to improve the wearing stability of high heels without changing the height, the influence of silicone insole on the stability of high heels was researched in this study. Methods: Selecting 24 female college students who had experienced wearing high heels, and then testing their balances of wearing 6cm high heels with three different structures of silicone insoles and those without insole by three -dimensional force plate named Kistler. Next, analyzing the balance parameters. Results: The static stability and dynamic stability of high heels with three silicone insoles were both higher than those without insoles. In addition, when the insoles were supported by arch, the sway velocity of COP would be lower than that of flat structure. Moreover, when the insoles with higher surface roughness, the maximum excursion of dynamic stability of high heels would be larger than that with lower roughness. Conclusion: Silicone insole can improve the wearing stability of high heels, and proper support on arch and texture design in surface can also improve the stability of high heels further.
