[0002] The shoe last is a mold used to form shoes. The design of the shoe last must be based on the shape of the foot, but it cannot be exactly the same as the foot, because the shape, size, stress, etc. of the foot will change when it is still and in motion. In addition, different shoes have different varieties, styles, processing techniques, properties of raw and auxiliary materials, wearing environments and conditions, etc., so the shape and size of each part of the shoe last cannot be exactly the same as the foot shape.

[0003] Most existing shoe lasts are of an integrated structure, and the shoe last and the corresponding shoe fit very tightly, making it difficult to remove the shoe last. Moreover, when removing the shoe last, it is necessary to pull hard, which easily causes wrinkles on the upper surface. Utility Model Content
