How do insoles improve stability in high-heel walking?

本研究的目的是了解鞋垫如何改善高跟鞋行走的稳定性。八名女性参加了五种不同的鞋子条件的实验：鞋跟形状、鞋垫形状和鞋垫摩擦。通过访谈收集穿着和穿着鞋子的主观评价。测量两种情况下的鞋内足压力、运动、行走时的地面反作用力。还测量了在平衡板上的平衡能力。结果表明，体重分布的感觉和摇摆脚跟的感觉是稳定性感知的感知原因。体重分布的感觉与足下的承重区域有关，而脚跟摇晃的感觉与脚跟的侧向倾斜（倒置）有关。我们检验了三个假设。实验结果表明，鞋垫提高稳定性的主要机制是通过增加支撑面积减少足部结构负荷。

The purpose of this study was to understand how insoles improve the stability in high-heel walking. Eight females participated in experiments using five different shoe conditions: heel shape, footbed shape, and friction of sockliners. Subjective evaluations of wearing and walking in the shoes were collected through interview. In-shoe foot pressure, motion, ground reaction force while walking were measured in each condition. Balancing ability on a balance board was also measured. Results showed that feelings of weight distribution and sensations of the wobbling heel were perceived causes of stability perception. Feelings of weight distribution were related to the weight-bearing area under the foot, and sensations of the wobbling heel were related to the lateral inclination (inversion) of the heel. Three hypotheses were examined. Results of the experiments indicated that the main mechanism of insoles for improving the stability was reduced load on foot structure caused by increased support area.
