Description

Technical Field

[0001] This utility model relates to the field of shoe last technology, specifically to a shoe last used for making sports shoes. Background Technology

[0002] A shoe last is the mold used to shape a shoe. It not only determines the shoe's shape and style but also its fit and ability to protect the foot. Current shoe last designs are often based on static foot shapes. However, since the foot shape differs between static and dynamic states, shoes made from lasts designed for static foot shapes often don't match the shape of the foot in motion, thus affecting comfort.

[0003] For example, Chinese patent application number 202220576275.X provides a shoe last for making athletic shoes. The shoe last has three interconnected regions along its front-to-back direction: a first region, a second region, and a third region. The first region extends from the front of the toes to the front of the arch, protruding downwards in the middle of its front-to-back direction. It also has two downwardly protruding recessed areas along the width of the shoe last, with the outer recessed area protruding higher than the inner one. The second region extends from the front of the arch to the front of the heel, concave upwards in the middle of its front-to-back direction and protruding downwards in the middle of its width. The third region corresponds to the heel area, protruding downwards in the middle of its front-to-back direction and downwards in the middle of its width. The lower surface of the shoe last has a smooth transition. This shoe last provides athletic shoes with high comfort, good support, and cushioning.

[0004] However, the following problems still exist in this technical solution: the shoe lasts in this technical solution are all molded in one piece. After the shoes are made, when it is necessary to remove the shoe lasts from the finished shoes, the shoe lasts are attached to the inner wall of the finished shoes, which will make it difficult to remove the shoe lasts.
