Description

Technical Field

[0001] This utility model relates to the field of shoe sole technology, specifically to a lightweight EVA foam shoe sole. Background Technology

[0002] EVA (ethylene-vinyl acetate copolymer) material has a low density. Foamed EVA soles made through a foaming process can significantly reduce weight while maintaining a certain strength. Compared with traditional rubber soles, foamed EVA soles can reduce weight by 30% to 50%, effectively meeting consumers' demand for lightweight soles. However, the existing soles have insufficient rebound, which greatly reduces running performance.

[0003] To address the aforementioned shortcomings, existing technology (Chinese patent publication number CN213307790U, publication date 2021-06-01) describes a supercritical physical foaming EVA shoe sole. This sole incorporates a rebound component, with connecting posts on the rebound component inserted into holes on the sole body for secure connection. The rebound force is increased by adding auxiliary components. The rebound component enhances the rebound effect because it has a protrusion on one side that extends downwards into a cavity within the sole body, pressing against the bottom of the cavity. The cavity is located on the heel side of the sole body. The rebound component itself has compressible rebound characteristics. When the heel exerts force, it first compresses the rebound component, which is then cushioned by the sole body. Some energy is stored in the rebound component, which rebounds to provide rebound force. This allows the sole to not only provide shock absorption and cushioning but also a certain degree of rebound force, improving the practicality of the shoe in daily life.

[0004] The above solution increases rebound by laying rebound elements in the sole during use. However, when a person walks, the force applied to the heel, arch, and ball of the foot is different. Laying the rebound elements flat is not enough to provide good support and force application for the sole, thus affecting the comfort during use. Utility Model Content

[0005] The purpose of this invention is to provide a lightweight foamed EVA sole to solve the problem mentioned in the background art that existing lightweight foamed EVA soles are not convenient for providing corresponding support and rebound to the foot according to the distribution of force application points of the heel, arch, and forefoot during use, thus affecting the comfort during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lightweight EVA foamed shoe sole, comprising a shoe sole body, wherein the bottom of the shoe sole body is provided with anti-slip patterns to increase grip, and the side edge of the shoe sole body is provided with reinforcing ribs;

[0007] An arch support is provided in the middle of the top surface of the sole body. The arch support supports the arch of the foot and maintains the normal force distribution of the foot.

[0008] A heel pad is installed on the top left side of the sole body, and the heel pad supports the heel;

[0009] The shoe sole has rebound components on the left and right sides of the inner middle part of the sole body, which provide rebound force to facilitate walking and running.

[0010] Furthermore, the arch support has a cavity in the middle and ventilation holes are equally spaced at the top of the arch support, and the cavity and ventilation holes are interconnected.

[0011] Furthermore, the heel pad is configured as a disc-shaped structure, and the heel pad has equally spaced grooves, in which massage magnetic beads are installed.

[0012] Furthermore, the reinforcing ribs are made of rubber and are connected in a crisscrossing mesh pattern, thus reinforcing and supporting the sole body.

[0013] Furthermore, the rebound component includes a first inner cavity opened inside the left side of the sole body, and a rebound block is installed in the first inner cavity. The rebound block is configured with a "U" shaped structure.

[0014] Furthermore, the rebound component also includes a second inner cavity opened inside the right side of the sole body, and rebound posts are evenly spaced inside the second inner cavity.

[0015] Furthermore, the rebound block and rebound column provide support and rebound for the heel and forefoot, respectively, and the rebound block, rebound column and reinforcing rib are made of the same material.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This lightweight EVA foam sole provides zoned support and rebound for the foot, addressing the different pressure points of the heel, arch, and forefoot during use. This enhances comfort when walking or running.

[0018] 1. Furthermore, the reinforcing ribs on the sides of the sole can reinforce the entire sole, and the arch support can provide good support for the arch of the foot, preventing flat feet and allowing the foot to exert force normally when walking and running.

[0019] 2. Furthermore, when the arch support is compressed, it will compress the cavity, and the air will be ejected from the vents, thus keeping the soles of the feet dry.

[0020] 3. Furthermore, the massage magnetic beads installed in the heel pad groove facilitate heel massage and relieve fatigue from walking for a long time;

[0021] 4. Furthermore, the rebound blocks in the first and second inner cavities can provide rebound force to the heel, and the rebound pillars can enhance the rebound of the forefoot area of ​​the sole body, so that when the sole body is used, it can provide rebound support to the sole of the foot in sections, improving the comfort and high rebound of the shoe.
