Inner shape footwear design of the patiens with diabetes

Abstract

This paper presents new principle of design and validates inner shape footwear designed specifically for people with diabetes. The shoe inner dimension provides the relevant inner dimensions for a particular shoe such as length, joint girth, instep girth, and any other dimension upon request. Is used by manufactures because it improves the design of shoe lasts, improves the accuracy of shoe production and the uniformity of the inner dimensions of shoes, and detects and analyzes undesired differences. However, tools for designing shoes for people with diabetes do not currently have the capacity to modify the last in order to reduce the risk of foot ulceration, whilst at the same time preserving the style of the shoe. The paper describes the procedures and the geometrical algorithms to handle the last geometry. Finally a case study is reported to show the advantages provided by the proposed approach in terms of achieved quality of the design process and expected footwear performance.
