Abstract: To improve the health of women's feet damaged by daily wearing high heels, 40 young women were selected to wear 3 pairs of high heels with full palm midsole material of different hardness. The Footscan^® plantar pressure measurement system was used simultaneously with RSscan^® force platform to test their gait cycle, center of pressure (COP) and plantar dynamics characteristics including maximum force, peak pressure, and pressure-time integral during natural walking. Results showed that, with the decrease in midsole hardness, the forefoot contact phase (FFCP) became longer, the foot flat phase (FFP) became shorter, the supination degree decreased significantly, and the pronation degree increased significantly. This study has important reference value for improving the comfort and stability of high-heeled shoes, and can provide scientific and reliable theoretical support for the selection and development of high-heeled midsole materials.
