Embodiment Construction

[0028] Embodiments are illustrated with drawings about this invention. The "inside-outside direction" in the following description means that the direction toward the foot of the shoe wearer is the "inside direction", and the direction toward the outside of the shoe is the "outside direction". In addition, in the following, when describing the shoe upper 2 before and after molding, it may also be expressed as the shoe upper 2A before molding and the shoe upper 2B after molding in order to distinguish them.

[0029] The shoe last (shoe mold) 1 of this embodiment is not mainly a shoe last for mass-produced products, but a customized shoe last 1 that fits the user's foot F. However, the present invention does not completely negate the application to shoe lasts for mass-produced products, but can also be applied. The shoe last 1 can be manufactured in a store that sells shoes, or it can be manufactured in a factory far away from the store by sending and receiving block joint data...

Abstract

The present invention addresses the problem of providing a reusable shoe last, a method for manufacturing a shoe last, and a method for manufacturing a shoe upper. A shoe last for forming an upper, the shoe last being provided with an aggregate of a plurality of masses at least on the outer peripheral part, the plurality of masses being capable of being coupled and separated from each other.

Description

technical field [0001] The present invention relates to a shoe last for molding shoe uppers, and also to a manufacturing method of the shoe last and a manufacturing method of the shoe upper. Background technique [0002] When making custom-made shoes that fit the user's feet, the shoe last is exclusive to the user, so after the shoe last is used to shape the shoe upper and the shoe is made, the shoe last is no longer needed except for the case where it is stored in advance for future use . [0003] US Patent Application Publication No. 2018 / 0014609 specification discloses manufacturing footwear in a portable housing. US Patent Application Publication No. 2016 / 0206049 discloses a shoe last preform capable of being reshaped by shape memory polymers. In Chinese patent application No. 109732913 specification, it is disclosed to form a shoe last by 3D printing. [0004] However, in each of the above-mentioned documents, there is no specific and clear disclosure about reusing u...
