Its core functions are to provide support, cushioning, and contact with the ground, and it needs to have properties such as wear resistance, slip resistance, water resistance, oil resistance, heat resistance, pressure resistance, impact resistance, and good elasticity.

[0003] The forefoot area of ​​existing shoe soles is the main area where the foot flexes and exerts force. In order to improve grip, anti-slip grooves or textures are set in the forefoot area of ​​the shoe sole. However, the structural design of anti-slip grooves or textures is generally only for the purpose of improving aesthetics, which can lead to complex anti-slip grooves or textures that can restrict the flexibility of the sole. Utility Model Content

A torsion support component is provided at the arch of the shoe sole body. The positioning edging is located at the top edge of the shoe sole body. The bending-reinforced anti-slip plate includes an anti-slip plate body, a bending groove connected to the center of the rear end of the anti-slip plate body, and two reinforcing grooves symmetrically arranged on the left and right sides of the bending groove. Each of the left and right sides of the anti-slip plate body is provided with at least one first connecting slot, and the front end of the bending groove extends to the middle section of the anti-slip plate body.

[0006] Furthermore, in order to increase the contact area and gripping force with the ground, the rear anti-slip plate has a horseshoe-shaped structure, and each of the left and right sides of the horseshoe-shaped structure is provided with at least one second connecting groove.

[0007] Furthermore, in order to improve the connection strength between the bending-reinforced anti-slip plate and the rear anti-slip plate, the bottom surface of the sole body is provided with a connecting block that fills the first connecting groove and the second connecting groove.

[0008] Furthermore, to enhance grip, the curved groove has a Y-shaped structure.

[0009] Furthermore, in order to optimize bending flexibility and drainage performance, the reinforced groove has a cross-shaped structure that bends toward the curved groove.

[0010] Furthermore, in order to improve the performance of arch bending, the torsion support component has a stepped groove on the inner wall, and the rear end of the groove extends into the front opening of the horseshoe-shaped rear anti-slip plate.

[0011] The beneficial effects of this utility model are: the sole adopts supercritical foaming technology, and the bending-reinforced anti-slip plate at the forefoot of the sole enhances the flexibility of the sole when bending during exercise through the cooperation of the bending groove and the reinforcement groove, while ensuring the grip when pushing off the ground.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example 1

[0015] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4This utility model provides a shoe sole technology solution using supercritical foaming technology: its structure includes a shoe sole body 1 formed by supercritical foaming and a positioning edge 2. A bending-reinforced anti-slip plate 11 is fixedly embedded at the forefoot of the shoe sole body 1, a rear anti-slip plate 12 is fixedly embedded at the heel of the shoe sole body 1, and a torsion support component 13 is provided at the arch of the shoe sole body 1. The positioning edge 2 is located at the top edge of the shoe sole body 1. The bending-reinforced anti-slip plate 11 includes an anti-slip plate body 111, a bending groove 112 connected to the center of the rear end of the anti-slip plate body 111, and two reinforcing grooves 113 symmetrically arranged on the left and right sides of the bending groove 112. The left and right sides of the anti-slip plate body 111 are each provided with at least one first connecting slot 114, and the front end of the bending groove 112 extends to the middle section of the anti-slip plate body 111.

[0016] The sole body 1 is manufactured using supercritical foaming, a physical foaming technology and a microporous foaming technology. In injection molding, extrusion, and blow molding processes, supercritical carbon dioxide or nitrogen or other gases are first injected into a special plasticizing device. After the gas is fully and uniformly mixed / diffused with the molten raw material, a single-phase mixed sol is formed. The sol is then introduced into the mold cavity or extrusion die, causing a large pressure drop in the sol, which causes the gas to precipitate and form a large number of bubble nuclei. During the subsequent cooling and molding process, the bubble nuclei inside the sol continue to grow and form, ultimately resulting in a microporous foamed plastic product.

[0017] The specific process flow is as follows: EVA particles are fed into a granulator, the material output from the granulator enters an injection molding machine, a cold mold is produced by the injection molding machine, and then the cold mold is foamed and formed by a vacuum foaming machine to produce a semi-finished product. The semi-finished product goes through the peeling, oil pressing, trimming and roughening processes in the secondary workshop in sequence to finally form the shoe sole body 1.

[0018] The sole body 1 has an assembly slot on its bottom surface that perfectly matches the shape and size of the bending reinforced anti-slip plate 11 and the rear anti-slip plate 12. The bending reinforced anti-slip plate 11 and the rear anti-slip plate 12 are connected to the corresponding assembly slot by adhesive or hot pressing.

[0019] To increase the contact area and gripping force with the ground, the rear anti-slip plate 12 has a horseshoe-shaped structure, and each of the left and right sides of the horseshoe-shaped structure is provided with at least one second connecting groove 121.

[0020] In order to improve the connection strength of the bending-reinforced anti-slip plate 11 and the rear anti-slip plate 12, the bottom surface of the sole body 1 is provided with a connecting block 14 that fills the first connecting groove 114 and the second connecting groove 121.

[0021] Among them, the bending-reinforced anti-slip plate 11 and the rear anti-slip plate 12 are both made of natural rubber or synthetic rubber, and have excellent anti-slip properties and wear resistance.

[0022] To improve grip, the curved groove 112 has a Y-shaped structure, with a groove depth of 1mm-10mm and a length of 30mm-60mm.

[0023] To optimize bending flexibility and drainage performance, the reinforcing groove 113 has a cross-shaped structure that bends toward the bending groove 112. When the forefoot bends, the reinforcing groove 113 deforms according to the angle of force to provide flexibility. Based on the characteristics of the cross-shaped structure, it ensures a certain degree of support performance after bending.

[0024] To improve the arch support performance, the torsion support component 13 has a stepped groove on the inner wall, and the rear end of the groove extends into the front opening of the horseshoe-shaped rear anti-slip plate 12. Example 2
