A CAD system for shoe last customization

Abstract

Customized shoes are desired in shoe industries nowadays to satisfy customer needs on style, fit and comfort. This paper proposes a CAD system for designing the customized shoe last based on the customer preferred shoe style and his/her foot features. Eighteen important foot features are firstly extracted from the laser-scanned foot data. The features are then used to deform the base shoe last of the customer preferred style to the customized shoe last with better fit to the customer's foot, while maximally maintaining the customer preferred style. Finally, the fit between the customer's foot and the customized shoe last is evaluated through a color-coded map.
