TECHNICAL FIELD

[0001] The utility model relates to a shoe accessory, especially a double-hardness shoe insole, shoe sole and shoe. BACKGROUND

[0002] The sole of a sports shoe usually comprises an insole and an outsole combined below the insole, and the insole usually has a certain softness to improve the cushioning and shock absorption performance of the shoe. However, the hardness of each area of the conventional insole is usually the same, the rebound speed after deformation is relatively slow, and the insole is prone to deformation after long-term use, affecting the service life.

[0003] There are also double-hardness shoe insoles on the market, such as the double-hardness shoe insole disclosed in the Chinese utility model patent CN220403245U, or the shoe with double-density insole disclosed in CN101912179A. However, the existing double-hardness shoe insole usually simply divides the shoe sole into upper and lower layers or front and rear zones, and sets different hardness for each layer or zone, which cannot solve the above problems.

[0004] Therefore, the applicant has conducted in-depth research on the structure of the shoe insole, and thus the present case is produced. CONTENT OF THE UTILITY MODEL

[0008] As an improvement of the utility model, the horizontal position of the upper end of the side wall is higher than that of the upper end of the core body.

[0009] As an improvement of the utility model, the hardness of the core body is 36-40 Shore hardness, and the hardness of the support body is 48-52 Shore hardness.

[0010] As an improvement of the utility model, the thickness of the support body is 0.5-3 mm.

[0011] As an improvement of the utility model, the support body is a transparent support body or a translucent support body.

[0012] As an improvement of the utility model, the upper surface of the core body is provided with a ventilation groove arranged along the width direction of the core body, and the end wall at both ends of the ventilation groove is respectively provided with a perforation, and the side wall is provided with a through hole in one-to-one communication with each perforation.

[0013] As an improvement of the utility model, the support body is provided with a groove arranged along the length direction of the support body, and the groove penetrates the support body up and down, and the circumferential side of the support body is provided with a plurality of damping holes in communication with the groove, and each damping hole is arranged in a staggered manner with each through hole.

[0014] As an improvement of the utility model, the groove is Y-shaped, and the head of the Y-shaped groove is located at the position corresponding to the front palm of the human palm.

[0015] A shoe sole comprises the shoe midsole, and the lower surface of the shoe midsole is compounded with a wear-resistant outsole.

[0016] A shoe comprises the shoe sole and the upper fixedly connected to the shoe sole.

[0017] By adopting the above scheme, the utility model has the following beneficial effects:

[0018] By arranging the side wall to cover the core body on the support body, the density of the two is different and they are fixedly connected with each other, when the core body is deformed under pressure, the side wall can bind the circumference of the core body to improve the stability, and after the pressure of the human palm on the core body is removed, the side wall can pull the core body to quickly reset, and the rebound speed is relatively fast, and since the binding effect of the side wall exists, the core body is not easy to deform, and the service life is relatively long.
