Abstract
The purpose of this study is to optimize the stiffness distribution of shoe sole under various moving speeds. The optimization is quantitatively evaluated by the propulsion impulse under each moving speeds. In other words, smaller propulsion impulse is equivalent with better shoes. The propulsion impulse is calculated by the forward ground reaction force. Forefoot bending stiffness makes a great influence on the propulsion impulse. Eigenfrequency analysis is applied to the sole stiffness evaluation. By using both the eigenfrequency analysis and ground reaction force measurements, the relationship between sole stiffness and the propulsion impulse under 3 moving velocity, 1.63m/sec, 1.91m/sec and 4.87m/sec are investigated. Therefore it was confirmed that the optimized sole stiffness distributions were affected by the moving speed.
