| Research Abstract |
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.
