Sports shoe with nondeformable elastic shoe rear upper

Abstract

The invention discloses a sports shoe with a nondeformable elastic shoe rear upper. The shoe comprises a sole and a shoe upper consisting of a shoe front upper, a shoe tongue and a shoe rear upper. The shoe rear upper consists of a high-elasticity ethylene vinyl acetate (EVA) elastic lining piece and a shoe rear upper body, wherein the lower end edge of the shoe rear upper body is combined with the edge of the sole of a heel part, the upper end edge of the shoe rear upper body extends upwards to the upper middle part of the shoe rear upper, and the rear middle part of the upper end edge has a middle notch. The rear middle part of the lower end edge of the elastic lining piece correspondingly has a middle convex part; the two ends of the elastic lining piece are connected with corresponding shoe ears respectively; and the lower end edge of the elastic lining piece is fixedly stitched with the upper end edge of the shoe rear upper body. The elastic lining piece of the shoe rear upper of the sports shoe is very elastic and soft and therefore can well keep the shoe rear upper straight and comfort; and the elastic lining piece is connected with the sole through the shoe rear upper body to prevent the elastic lining piece from being broken when the shoe rear upper is depressed and deformed because the elastic lining piece only distorts when the shoe rear upper is depressed and deformed and can restore automatically with high elasticity to keep the shoe rear upper straight.

Description

technical field [0001] The invention belongs to sports shoes, in particular to a sports shoe with a non-deformable elastic back upper. Background technique [0002] The structure of existing various sports shoes mainly includes: the sole, which is located at the bottom of the shoe; , the tongue is a tongue-shaped part installed on the back of the tarsus, and the back of the shoe is the rear part of the upper that surrounds the heel. The back of the shoe is required to have a certain upright elasticity to prevent the back of the shoe from collapsing and deforming when it is put on and off. It is directly fixedly connected with the heel sole, and the back of the shoe can be upright through the elasticity of the hard elastic heel piece. But because the heel piece is made of hard elastic material, it is uncomfortable to wear; the heel piece and the sole are directly fixedly connected, and the connection between the heel piece and the sole is prone to deformation, wrinkles and ...
