[0002] The shoe last, a traditional Chinese shoemaking tool, is the mother of the shoe, the mold that forms the shoe. It not only determines the shape and style of the shoe, but also its fit and foot protection. Therefore, shoe last design must be based on the foot's shape, but it cannot be identical to the foot itself. This is because the foot's shape, size, and stresses vary both at rest and in motion. Furthermore, shoe types, styles, processing techniques, raw material properties, and wearing environments and conditions vary. Therefore, the shape and dimensions of each component of the shoe last cannot be exactly the same as the foot itself. Therefore, modern shoe last design involves multiple disciplines and requires a high level of craftsmanship and experience.

[0003] As demand for shoes increases, shoe production needs to increase, and the durability of shoe lasts used in shoe manufacturing also needs to be improved. However, existing shoe lasts lack a durable structure. Under long and intensive shoemaking cycles, the wear and breakage rate of shoe lasts increases significantly, necessitating the development of a high-strength shoe last. Utility Model Content
