Technical Field

[0001] The utility model relates to the field of shoe soles, in particular to an ultra-light EVA shoe sole. Background Art

[0002] EVA soles refer to soles made of ethylene-vinyl acetate copolymer materials. They are light in weight and easy to wear. Existing EVA soles often hollow out the internal structure of the soles in pursuit of quality, which will further reduce the support of the EVA soles, reduce the wearing experience, and shorten the service life of the shoes. Utility Model Content

[0003] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by implementing the utility model. The purpose and other advantages of the utility model can be realized and obtained through the structures specifically pointed out in the description and the drawings of the description.

[0004] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide an ultra-light EVA sole, which has the advantages of reducing the deadweight of the sole while improving the support and wearing comfort of the sole.

[0005] The utility model provides an ultra-light EVA sole, comprising a sole body and an elastic reinforcement member. The sole body is horizontally provided with an active groove with an opening facing backward at the heel position of the shoe, and the elastic reinforcement member is arranged along the top, one side wall and the bottom of the active groove. When the elastic reinforcement member is subjected to pressure, the distance between the top position and the bottom position of the elastic reinforcement member near the opening of the active groove gradually decreases, and the elastic reinforcement member returns to its original shape after the pressure is lost.

[0006] In some embodiments, the elastic reinforcement member is provided with a triangular reinforcement member between the top and the side wall.

[0007] In some embodiments, the sole further includes a return spring, which is disposed in the elastic reinforcement member and located on a side close to the opening of the movable groove.

[0008] In some embodiments, the top and bottom of the elastic reinforcement member are provided with connection holes, and the two ends of the return spring pass through the upper and lower connection holes respectively and are fixedly connected to the sole body.

[0009] In some embodiments, the bottom of the sole body is provided with an upwardly protruding cavity at the center of the forefoot.

[0010] In some embodiments, a plurality of grooves are provided at the bottom of the sole body.

[0011] By adopting the above technical solution, the beneficial effects of the utility model are:

[0012] The utility model opens a movable groove at the rear side of the sole and arranges an elastic reinforcement member along the inside of the movable groove, thereby reducing the deadweight of the sole and increasing the rebound ability of the heel position of the sole by using the elastic reinforcement member, thereby improving the supporting force of the sole; the structural strength of the elastic reinforcement member is increased by arranging a triangular reinforcement member; the resetting condition of the elastic reinforcement member is increased by arranging a resetting spring; an upwardly convex cavity is arranged to weaken the hard contact of the forefoot part of the sole and improve the wearing comfort; and a groove is arranged to reduce the deadweight of the sole and increase the friction of the sole.

[0013] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure.

[0014] Undoubtedly, these and other objects of the present invention will become more apparent after the following detailed description of the preferred embodiments described with reference to various figures and drawings.

[0032] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model, but not to limit the utility model.

[0033] Reference Figure 1-4 The utility model provides an ultra-light EVA sole, comprising a sole body 1, an elastic reinforcement member 2 and a return spring 3.

[0034] The sole body 1 is horizontally provided with an opening rearwardly-facing movable groove 11 at the heel position, and the movable groove 11 makes the sole body 1 Y-shaped when viewed from the side. The elastic reinforcement 2 is arranged along the top, side wall and bottom of the movable groove 11, and the elastic reinforcement 2 is preferably made of carbon fiber material. After the elastic reinforcement 2 is subjected to pressure, the distance between the top position and the bottom position of the elastic reinforcement 2 and the side near the opening of the movable groove 11 gradually decreases, and the elastic reinforcement 2 returns to its original shape after losing pressure. The elastic reinforcement 2 is provided with a triangular reinforcement 21 between the top and the side wall. The reset spring 3 is arranged in the elastic reinforcement 2 and is located on the side near the opening of the movable groove 11. The top and bottom of the elastic reinforcement 2 are both provided with connecting holes 22, and the two ends of the reset spring 3 are respectively fixedly connected to the sole body 1 through the upper and lower connecting holes 22. The bottom of the sole body 1 is provided with an upwardly protruding cavity 12 at the forefoot palm position. The bottom of the sole body 1 is provided with a plurality of grooves 13.

[0035] Working principle: During use, the elastic reinforcement 2 increases the rebound ability of the heel, and the cavity 12 and the ground form a temporary air cavity to provide cushioning for the forefoot.
