Digitization is the premise of realizing intelligent manufacturing, and how to promote the informationization of technical resources and demand matching is the key to realize accurate customization of footwear products. Foot-last relationship is the core issue in the process of shoe customization, and most of the previous researches focus on the induction of foot features and classification and the improvement and reconstruction of local parameters of lasts, lacking the research of forming a data-driven full informatization system by linking foot-last model features. Through the research on special cross-section, the inductive construction of bunion foot feature data model and the linking of features of common model of sports shoes last, for example, an all-in-one informationized intelligent identification design system is built, which realizes the shift of traditional footwear design process and data, improves the subjective "empirical" design mode in traditional footwear industry, and provides informationization for It improves the subjective "empirical" design mode in the traditional footwear industry and provides an information-based realization path for footwear precision customization service.
