Last xié xuàn Last is the mother of shoes. This is the mold for shoes. Last not only determines the shape and style of shoes, but also determines whether the shoes fit and protect the feet. Therefore, the design of shoe last must be based on the foot type, but it can't be exactly the same as the foot type, because the shape, size and stress of the foot change when it is at rest and moving, and the variety, style, processing technology, performance of raw and auxiliary materials, wearing environment and conditions of the shoe last are also different, so the shape and size of each part of the shoe last can't be exactly the same as the foot type. Therefore, modern shoe last design not only involves many disciplines, but also requires very high manual skills and experience.
