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

[0008] A liquid injection hose corresponding to the second liquid injection pipe is provided inside the expansion tube, and a plurality of deformation notches are provided 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 is provided on the inner side of the sealing band to seal and position the inlet of the liquid injection channel.

[0011] Furthermore, in order to improve the firmness of the connection, the closing band and the sole are connected by one of hot 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 tapered structure.

[0015] Furthermore, in order to improve the stability of the connection, the protective part and the upper are connected by a method selected from the group consisting of hot pressing, gluing, and sewing.

The protective portion 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 based on the protection demand value provided by the consumer. The elastic rubber structure enters the expansion pad through the injection channel. After filling, 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 and deforms outward. After the elastic rubber structure solidifies, the overall elasticity and protective performance of the protective portion are improved. BRIEF DESCRIPTION OF THE DRAWINGS
