Evaluation Fitness of Footwear Using Hybrid Simulation

Abstract:

This research is trying to develop a process for identifying comfortable shoe last for human feet. A hybrid of geometric model and physics based model is proposed to simulate the procedure of fitting foot into footwear. The system implemented is able to construct all meaningful slicing planes used in footwear industry. And all kinds of dimensions are measured for fitness check, especially the most important three girth of human feet and shoe last, i.e., ball girth, waist girth, and instep girth. Quantified Fitness range, known as dimensional difference (DD), is updated according to positive and negative samples. Result shows that comparing with geometric based method, our method significantly improves the percentage of comfortable shoes among all shoes that are guided by former fitness evaluation method.
