In the designing process of running shoes, it is important to evaluate their performance of several key functions, including cushioning, stability and fitting. The methods used in these evaluation should be simple in order to cut cost and save time. The purpose of this study is to develop a simple evaluation method for running shoes stability. The new evaluation method is based on the center of pressure displacement in the shoe medial direction (dx) during the support phase of running. Three runners with different gait patterns were analyzed and the relationship between ankle joint angles and dx were considered. All results indicate a significant correlation between maximum heel eversion angle and dx at the appearance time of local minimum value on vertical ground reaction force. Furthermore, for the application of the practical shoes designing, we consider the effect of localized sole dent positions on dx. It is confirmed that a localized dent in the rear medial side is effective for stability improvement.
