The shoes is made by injecting the polymer resin into the mold. The polymer resin is the thermoplastic polyether ester block copolymer resin with the bending elasticity of 500-5,000 kg/cm3. The polyether ester resin is copolymerized with polybutylene terephthalate as the crystalline component and polyalkyllene oxide glycol as the rubbery component.
