Description

Technical Field

[0001] This utility model relates to the field of casual shoe technology, specifically a high-elasticity casual shoe with a combination of large-hole EVA and rubber sole. Background Technology

[0002] Casual shoes are a type of footwear characterized by their simple and comfortable design, meeting the needs of people's daily wear. The concept, connotation, and function of casual shoes are closely related to the lifestyle and pursuits of modern people. People use the style, brand, and connotation of casual shoes to decorate and present themselves, gaining aesthetic pleasure and symbolic spiritual satisfaction. With the development of society, people's requirements for shoes are getting higher and higher. They not only require shoes to be beautiful and comfortable, but also have higher requirements for other performance aspects. The large-pore EVA in casual shoes usually refers to EVA sole material with an open-pore foam structure.

[0003] The large-pore EVA used in existing casual shoes generally refers to the interconnected honeycomb-like pores inside the sole, forming an open mesh channel. This structure allows air and moisture to circulate freely, similar to the physical form of a sponge. EVA, as a lightweight and highly elastic polymer, forms a porous structure through a foaming process. The vinyl acetate component in its molecular chain gives the material flexibility and impact resistance. Therefore, it is generally used in the outsole and other parts of casual shoes that come into contact with the ground to ensure the elasticity of the sole.

[0004] While the aforementioned existing technologies have significant beneficial effects, they still have shortcomings:

[0005] While the aforementioned casual shoes utilize large-pore EVA as the outsole structure, providing high resilience, tensile strength, and high toughness, thus ensuring high elasticity and improving wearing comfort, the sole's slip resistance is limited due to the reliance on raised sections. Furthermore, the limited abrasion resistance of the EVA material leads to wear and tear on the slip-resistant structure over time, compromising safety. Therefore, a high-elasticity casual shoe combining large-pore EVA and rubber in the sole is proposed. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a high-elasticity casual shoe with a combination of large-pore EVA and rubber sole. The outsole structure uses a large-pore EVA base layer as the outsole material, and the rubber base layer, which is embedded in the bottom surface and bonded together, enhances the friction and anti-slip properties of the bottom surface, thereby achieving the purpose of high elasticity, anti-slip and wear-resistant properties.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-elasticity casual shoe with a large-hole EVA and rubber composite sole, comprising a shoe body, a composite outsole glued and fixed to the bottom end of the shoe body, a heel reinforcement surface sewn to the rear end of the shoe body, the composite outsole comprising an EVA base layer, a composite groove formed on the top surface of the EVA base layer, protruding strips distributed on the top surface of the composite groove, a thickened base layer fixed to the other side of the top surface of the composite groove, connecting edges connected to the four perimeters of the top surface of the composite groove, a rubber base layer adhered to the bottom surface of the EVA base layer, embedded studs distributed on the top surface of the rubber base layer, and anti-slip grooves distributed on the bottom surface of the rubber base layer.

[0008] Preferably, the rubber sublayer is uniformly bonded and fixed along the bottom surface of the EVA sublayer, and the rubber sublayer is embedded in the bottom surface of the EVA sublayer through embedded posts.

[0009] Preferably, the EVA bottom layer is bonded to the bottom surface of the shoe body through a combination groove, and the connecting edges around the combination groove are sewn and fixed to the bottom surface of the shoe body.

[0010] Preferably, the shoe body includes an upper body, the front end of the upper body is sewn with a forefoot surface, the rear end of the upper body is sewn with a heel surface, the sides of the heel surface are attached to the sides of the heel surface, and a shoelace is threaded through the top surface of the forefoot surface.

[0011] Preferably, the upper body is sewn and fixed to the forefoot and heel surfaces, and its side surfaces are symmetrically distributed along the two sides of the upper body.

[0012] Preferably, the heel reinforcement surface includes an upper heel surface, the bottom surface of which is attached to a lower heel surface, the inner walls of the lower heel surface and the upper heel surface are attached to the shoe body and the combined outsole, and the edges of the lower heel surface and the upper heel surface are sewn with a heel seam.

[0013] Preferably, the lower heel surface and the upper heel surface are stitched and fixed to the shoe body and the base of the combined outsole by a root stitch.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention uses a large-pore EVA bottom layer as the outsole structure, which provides high resilience, tensile strength and high toughness for the overall casual shoe sole. The thickened bottom layer of the EVA bottom layer further increases the elasticity of the bottom. At the same time, the rubber bottom layer, which is fixed and bonded together with the embedded piles on the bottom surface, improves the friction and anti-slip properties of the bottom surface, thereby achieving the purpose of high elasticity and anti-slip and wear-resistant properties, making it convenient and comfortable to wear.

[0016] These high-elasticity casual shoes feature an upper formed by stitching the upper and heel together with the sides of the shoe. The laces ensure stability when the shoe is tightened, while the sides of the shoe maintain the stability of the stitched upper structure, making them easy to wear and use.

[0017] These high-elasticity casual shoes maintain a stable connection at the heel by stitching the upper and lower heel surfaces together with the heel surface and the EVA bottom layer, ensuring stability during strenuous exercise.

[0018] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures pointed out in the description, claims, and drawings. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4This embodiment of a high-elasticity casual shoe with a large-hole EVA and rubber composite sole includes a shoe body 1, a composite outsole 2 glued and fixed to the bottom end of the shoe body 1, a heel reinforcement surface 3 sewn to the rear end of the shoe body 1, the shoe body 1 includes an upper body 101, a forefoot upper 102 sewn to the front end of the upper body 101, a heel surface 103 sewn to the rear end of the upper body 101, shoe side panels 104 attached to both sides of the heel surface 103, and a shoelace 105 threaded through the top surface of the forefoot upper 102.

[0026] like Figure 1-4 As shown, the high-elasticity casual shoe of this utility model is similar in structure to existing casual shoes. The main improvement of this utility model is that it uses a large-pore EVA bottom layer 201 as the outsole structure, and relies on the embedded piles 207 on the bottom surface to embed and bond the rubber bottom layer 206 to improve the friction and anti-slip properties of the bottom surface, thereby achieving the purpose of high elasticity and anti-slip and wear-resistant properties. In this utility model, both the EVA bottom layer 201 and the shoe body 1 are existing technologies. When using this high-elasticity casual shoe, the user can directly loosen the shoelaces 105 on the outer wall of the shoe tongue to wear and use it, and then tighten the shoelaces 105 to complete the wearing process. The casual shoe has the front upper 102 and the heel surface 103 sewn together with the two side shoe sides 104 to form the upper body 101. The shoelaces 105 can keep the wearing stability after tightening, while the two side shoe sides 104 can keep the sewn upper structure stable, thus facilitating wearing and use.

[0027] like Figure 1-3 As shown, the composite outsole 2 includes an EVA base layer 201. A composite groove 202 is formed on the top surface of the EVA base layer 201. Outer protrusions 203 are distributed on the top surface of the composite groove 202. A thickened base layer 204 is fixed to the other side of the top surface of the composite groove 202. Connecting edges 205 are connected to the four perimeter of the top surface of the composite groove 202. A rubber base layer 206 is attached to the bottom surface of the EVA base layer 201. Embedded posts 207 are distributed on the top surface of the rubber base layer 206. With anti-slip grooves 208 distributed throughout, this casual shoe uses a large-pore EVA bottom layer 201 as the outsole structure, which provides high resilience, tensile strength and high toughness to the overall casual shoe sole. The thickened bottom layer 204 of the EVA bottom layer 201 further increases the elasticity of the bottom. At the same time, the rubber bottom layer 206, which is embedded and fixed by the bottom embedded studs 207 and bonded together, improves the friction and anti-slip properties of the bottom surface, thereby achieving the purpose of high elasticity and anti-slip and wear-resistant properties, making it convenient and comfortable to wear.

[0028] The aforementioned EVA bottom layer 201 maintains stable friction after being bonded to the bottom of the upper body 101 via the outward protrusion strip 203. Meanwhile, the connecting edges 205 around the EVA bottom layer 201 can maintain a close fit with the bottom of the upper body 101. Together with the stitching, they form a double fixation of bonding and stitching, improving the stability of the connection structure.

[0029] like Figure 4 As shown, the heel reinforcement surface 3 includes an upper heel surface 301, and a lower heel surface 302 is attached to the bottom surface of the upper heel surface 301. The inner walls of the lower heel surface 302 and the upper heel surface 301 are attached to the shoe body 1 and the combined outsole 2. The edges of the lower heel surface 302 and the upper heel surface 301 are sewn with a root stitch line 303. The casual shoe maintains the connection stability at the root by sewing the upper heel surface 301 and the lower heel surface 302 with the root stitch line 303 to the heel surface 103 and the EVA bottom layer 201, which facilitates stability during vigorous exercise.

[0030] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
