It is very useful for designing suitable high heels that we investigate the biomechanical characteristics of a woman’s trunk and lower limbs , who is walking with high heehs. This paper summarizes the common impairment caused by high-heels, including platypodia, toe deformity, sprain of ankle,gonarthritis,backache. The gait characters of walking women in high heels are with little stride, low step speed, long gait cycle, more fluctuant center of gravity, shorter phase of single-limb stance. The characters on mechanics shows that the pressure on pelma is not even, the stress at knee joint increases, the muscle power of lower limbs gets weak, and even the load on spine augments. Therefore woman walking in high heels for a long time causes a lot of adverse effects on trunk and lower limbs, that means a woman should wear high heels as few as possible in daily life.
