Description

Insole for cushioning sole

Technical Field

The utility model relates to an insole for a cushioning sole.

Background

The existing sports shoes mostly adopt the cushioning sole, the cushioning sole can play a role in buffering and protecting the foot, impact on the foot in the moment of falling to the ground after jumping is reduced, but in the moment of jumping and during running, as the cushioning sole has the function of relieving, the jumping force is reduced, the jumping height is reduced, and the running is more laborious.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing an insole for a cushioning sole, which has the advantages of good elasticity, uniform stress and difficult stress release.

In order to solve the technical problems, the utility model provides an insole for a cushioning sole, which comprises an insole main body made of high-elasticity EVA materials, wherein the insole main body is divided into the following functional areas from front to back: toe portion, sole portion, arch portion and heel portion, the toe portion of shoe-pad main part is the same with sole portion thickness, heel portion thickness is greater than sole portion thickness, the arch portion upside of shoe-pad main part corresponds arch portion position and has the structure that is used for laminating the arch of foot upwards uplifting, shoe-pad main part upside corresponds heel position and is equipped with the recessed structure that is used for wrapping the heel, the sole portion of shoe-pad main part, the insole comprises an insole body, a sole, a heel part, a foot arch part, a heel part and a cushioning pad layer, wherein the arch part and the heel part are in smooth transition, an upper concave groove is formed in the lower side position of the insole body corresponding to the contact area of the arch part, the sole part and the toe part with the thumb, a carbon fiber plate matched with the groove in shape is arranged at the groove bottom of the groove, a supporting frame is arranged on the lower side of the circumferential edge of the carbon fiber plate and connected with the insole body, an extending part extending backwards and wrapping the heel part of the insole body is arranged on the rear side of the supporting frame, and the cushioning pad layer made of PU material is arranged on the lower side of the extending part; the upper side of the insole main body is provided with an antibacterial non-woven fabric layer, and anti-skid rubber particles are arranged at the upper side position of the antibacterial non-woven fabric layer corresponding to the toe part and the sole part.

For the sake of simplicity, the insole for cushioning sole according to the present invention is hereinafter referred to simply as the present insole.

The insole has the advantages that: the whole shape of the insole is more fit with the sole, the carbon fiber plate covers the springing position and the force-exerting position of the foot during running, the carbon fiber plate is stressed and deformed when the foot exerts force, then the resilience force of the carbon fiber plate can be used as the power during running or bouncing, the defects of reduced springing height and labor-consuming running caused by the effect of relieving the sports shoes with the cushioning soles are prevented, in addition, the carbon fiber plate also plays a role of average stress, the single-point pressure of the ground acting on the foot can be diffused into the whole-face average stress by the carbon fiber plate, so that the foot can not be impacted by larger pressure, the protection effect is achieved, the cushioning cushion layer can play a double-layer cushioning effect with the cushioning soles at the heel parts, the personnel foot injury caused by overlarge impact force when the heel is contacted with the ground during sports, the antibacterial non-woven fabric layer can play a role of preventing the breeding of bacteria and fungi, the anti-skidding rubber particles on the upper side of the antibacterial non-woven fabric layer can reduce the possibility of sliding between the foot and the insole when the foot moves to exert force, and the risk of stress relief and foot sprain caused by sliding between the foot and the insole is prevented.
