Document Type and Number:
WIPO Patent Application WO/2012/138084
Kind Code:
A3
Abstract:
The present invention relates to a lightweight shoe manufactured without an adhesive process. According to the lightweight shoe, an adhesive property and a function for preventing sliding are provided, regardless of the various shapes and configurations of the wearers' feet. The lightweight shoe includes: a bottom material including an insole contacting a sole, wherein the insole has a mesh structure and is formed of a fiber material, and an outsole formed of thermoplastic elastomer (TPE), wherein the outsole is coupled to the insole by injection molding; and a leather upper coupled to the outsole through sewing, wherein the leather upper is formed of an elastic fiber having an elastically restoring force of about 120% to about 150%. Thus, since an adhesive is not used, the lightweight shoe may be environmentally friendly, and workers' productivity may be improved. Also, since the shoe is super-lightweight, bare foot walking may be maximally felt to give maximum wearability to the shoe wearer.
