ABSTRACT

The design of foot arch is a critical issue for manufacturing comfort and satisfied shoes. Traditionally, linear dimensions, just like arch height, are applied to describe the shape of arch. However, it is inappropriate to describe 3D geometric features with 1D data. Furthermore, the 3D change of arch is not so clear. The main purpose of this study was to discuss the change of arch during different weight-loading with foot 3D scanned data. A 3D Scanner was used to collect the three-dimensional foot models by scanning subject’s foot and then construct relevant 3D feet models. The volunteers who aged from 18 to 25 were undergraduate and graduate students. Three levels of loading were considered, 0%, 50% and 100% of body weight. With the 3D scanned data, the size and trend of change on geometric features of arch during different loading levels will be obtained. The data of length curvature, circumference, area, angle and volume were collected from the 3D scans and were analyzed to discover the change and variation of arch during different weight-loading. According to the result, the features and trend of variation for arch at different loading weight were more obvious.
