[0007] The protective part is wrapped around the rear end of the upper;

[0008] A liquid injection hose corresponding to the second liquid injection pipe is arranged inside the expansion tube, and a plurality of deformation notches are arranged on the inner wall of the expansion tube.

[0009] Furthermore, in order to prevent the injected glue from flowing back, a check valve is provided at the inlet of the injection channel.

[0010] Furthermore, in order to prevent the inlet of the liquid injection channel from being exposed, a sealing block for sealing and positioning the inlet of the liquid injection channel is provided on the inner side of the sealing belt.

[0011] Furthermore, in order to improve the firmness of the connection, the closing band and the sole are connected by one of heat pressing, gluing and sewing.

[0012] Furthermore, in order to facilitate deformation under pressure, the expansion pad and the expansion tube are both made of silicone material.

[0013] Furthermore, in order to adjust the U-shaped air cushion during deformation, the expansion cushion is in the shape of a cylindrical structure.

[0014] Furthermore, in order to increase the deformation range, the deformation notch is a conical structure.

[0015] Furthermore, in order to improve the stability of the connection, the protective part and the upper are connected by one of hot pressing, gluing and sewing.

[0016] Furthermore, in order to prevent wear, the outer wall of the closing belt has anti-wear grooves.

[0017] Furthermore, in order to improve the protective effect, the expansion pad and the injection hose are filled with an elastic rubber structure, and the elastic rubber structure is specifically one of natural latex and polyurethane elastic emulsion.

[0018] The beneficial effects of the present invention are as follows: an integrally formed protective part is provided on the sole, and the protective part supports and wraps around the heel of the shoe upper, which can effectively prevent the shoe from falling off and improve firmness. The protective part can be used to customize the protective effect according to the needs of the wearer. The manufacturer injects a corresponding amount of elastic rubber structure according to the protection demand value provided by the consumer. The elastic rubber structure enters the expansion pad through the injection channel. After the filling is completed, the excess elastic rubber structure enters the injection hose in the expansion tube through the second injection tube. Under the action of the injection hose, the expansion tube expands outward and deforms. After the elastic rubber structure solidifies, the overall elasticity and protective performance of the protective part are improved. BRIEF DESCRIPTION OF THE DRAWINGS
