[0027] The exemplary embodiments of the present invention will now be described more fully with reference to the accompanying drawings. However, it should not be understood that the implementation of the present invention is limited to the embodiments described herein. The same reference numerals in the figures represent the same or similar structures, and thus their repeated descriptions will be omitted.

[0028] The utility model provides a sole which can be used as the sole of children's comprehensive training shoes. Figures 1 to 6 The structure of the sole according to the present invention is described in detail.

[0029] like Figures 1 to 6 As shown in FIG, a sole according to the present invention may include a sole body 10 having a sole portion 110, a heel portion 120, and a connecting portion 130 connecting the sole portion 110 and the heel portion 120. A first groove 111 is formed in the upper surface of the sole portion 110, and a second groove 121 is formed in the upper surface of the heel portion 120. The sole includes a first high elastic sheet 100 and a second high elastic sheet 200 respectively embedded in the first groove 111 and the second groove 121. According to an embodiment of the present invention, the sole body 10, the first high elastic sheet 100 and the second high elastic sheet 200 may all be made of EVA (ethylene-vinyl acetate copolymer) material, and the elasticity of the first high elastic sheet 100 and the second high elastic sheet 200 is greater than the elasticity of the sole body 10.

[0030] The shoe sole body 10 can be made of a brand-new EVA material, for example, the molecular structure and physical properties of the EVA material are optimized. Specifically, for example, by adjusting the content of vinyl acetate and adding specific additives, the elastic modulus and resilience of the EVA material are enhanced, and through a large number of simulation tests and actual sample trial production, the best combination of meeting the shock absorption performance requirements while considering the durability and stability of the material is determined, thereby being able to buffer the foot pressure, for example, according to the intensity and angle of each landing, the deformation degree is adaptively adjusted, ensuring that the foot is always in a relatively comfortable stress environment, reducing the damage to the joints and muscles of the foot during long-term walking, and providing continuous and stable shock absorption protection for the user.

[0031] In addition, the first high-elasticity sheet 100 and the second high-elasticity sheet 200 embedded in the shoe sole body 10 can enhance the buffering effect and give rapid energy feedback and enhance the sports ability. The high-elasticity sheet deforms elastically under the action of impact force, absorbs and stores part of the impact force as elastic potential energy, can reduce the impact force transmitted to the foot and joint, reduce the risk of sports injury, and at the same time, the elastic potential energy can be converted into kinetic energy to provide additional thrust to the foot, helping children to take the next step more easily, thereby helping children to reduce fatigue and improve sports efficiency in sports.

[0032] According to the preferred embodiment of the utility model, the thickness of the first high-elasticity sheet 100 and the second high-elasticity sheet 200 can be substantially the same. For example, the thickness of the first high-elasticity sheet 100 and the second high-elasticity sheet 200 can be 4mm or 5mm, thereby improving the energy feedback capability of the shoe sole while ensuring the comfort of the shoe sole.

[0033] However, the embodiments of the utility model are not limited thereto, since the shoe sole thickness of different age groups can be different, therefore, the thickness of the first high-elasticity sheet 100 and the second high-elasticity sheet 200 can also be changed according to the shoe sole thickness of the corresponding part. For example, according to the embodiment of the utility model, the thickness of the first high-elasticity sheet 100 can be 1 / 3 to 2 / 3 of the thickness of the instep part 110, and / or the thickness of the second high-elasticity sheet 200 can be 1 / 5 to 2 / 5 of the thickness of the heel part 120.

[0034] Generally, the thickness of the instep part 110 is thinner than the thickness of the heel part 120, therefore, the thickness of the first high-elasticity sheet can be about 1 / 2 of the thickness of the instep part 110, in this case, the thickness of the second high-elasticity sheet 200 can also be the same as the thickness of the first high-elasticity sheet 100.

[0035] In addition, according to the embodiment of the utility model, the area of the first high-elasticity piece 100 can be set to 1 / 3 to 1 / 2 of the area of the instep part 110; and / or, the area of the second high-elasticity piece 200 can be set to 1 / 3 to 1 / 2 of the area of the heel part 120. Here, since the shapes of the instep part and the heel part are not regular shapes, the above-mentioned area ratio can be a range roughly calculated visually, ensuring that the first high-elasticity piece 100 and the second high-elasticity piece 200 neither cause the sole to be too hard due to excessive area, resulting in poor comfort, nor fail to improve the sports ability due to the area of the high-elasticity piece being too small.

[0036] As shown in Figure 1 According to the preferred embodiment of the utility model, the shape of the first high-elasticity piece 100 can have a trapezoidal shape with chamfered corners, and the second high-elasticity piece 200 can have a rectangular shape with rounded corners, so as to be roughly fitted to the shapes of the instep part 110 and the heel part 120.

[0037] As shown in Figure 4 and Figure 5 The depth of the first groove 111 is the same as the thickness of the first high-elasticity piece 100, and the depth of the second groove 121 is the same as the thickness of the second high-elasticity piece 200, so that the sole has a flat upper surface.

[0038] In addition, according to the embodiment of the utility model, the sole can further include an anti-twist piece 300 arranged in the connecting part 130 and between the first high-elasticity piece 100 and the second high-elasticity piece 200. During movement, the foot part will produce a twisting action, and the anti-twist piece 300 can effectively limit the over-twisting of the sole and provide stable support for the foot part.

[0039] According to the embodiment of the utility model, the anti-twist piece 300 can be arranged spaced apart from the first high-elasticity piece 100 and the second high-elasticity piece 200, and the thickness of the anti-twist piece 300 can be thinner than the thickness of the first high-elasticity piece 100 and the second high-elasticity piece 200. For example, the thickness of the anti-twist piece 300 can be set to 2.5mm-3mm.

[0040] In addition, according to the embodiment of the utility model, in order to enhance the grip of the sole and improve the anti-skid and wear-resistant performance, a rubber part 400 is further arranged on the bottom surface of the sole body 10, which can be designed in the form of independent modules respectively located at the forefoot and hindfoot parts. Each module is designed with corresponding pattern shape and depth according to the functional requirements and stress characteristics of different parts of the sole. In addition, in order to reduce the weight of the sole, the rubber part 400 can be arranged in a hollow form. At the same time, in order to enhance the wear-resistant performance of the side edge, the rubber part 400 can extend from the bottom surface of the sole body 10 to part of the side surface.

[0041] According to another aspect of the present application, a shoe (not shown) including the shoe sole is provided, the shoe further including an upper, the upper can include a three-layer structure formed by three different materials. According to an embodiment of the present application, the three-layer structure includes a jacquard upper layer, a support layer and a knitted material layer. The jacquard upper layer can form at least a portion of the outer surface of the shoe, the knitted material layer can form at least a portion of the inner surface of the shoe, and the support layer is arranged between the jacquard upper layer and the knitted material layer.

[0042] The jacquard upper layer has excellent firmness and wear resistance, can effectively protect the overall structure of the upper, and prolong the service life of the upper. The support layer plays a key supporting role, by selecting a support layer with appropriate hardness and elastic modulus, the corresponding support force can be provided according to the shape change of the foot during movement and walking, so as to ensure that the upper will not be deformed too much due to external force, maintain the shape stability of the upper as a whole, and improve the comfort of wearing. The knitted material layer is closely combined with the jacquard upper layer and the support layer, which can improve the problem of relatively soft pure jacquard upper on the basis of meeting the ventilation demand, so that the entire upper is more soft and comfortable in touch, and more fits the foot. The three layers are connected by a specific composite process (for example, hot pressing and fitting technology), so as to ensure that the layers are closely fitted and will not be layered during use, and to ensure that the layers can play their independent functional characteristics, and realize the synergistic optimization effect of the entire upper structure in softness, air permeability and wear resistance.

[0043] In addition, according to an embodiment of the present application, in order to realize the light weight of the upper, a TPU (thermoplastic polyurethane) film hot cutting process can be used to realize the seamless appearance effect. In addition, the thickness of the selected TPU film can be much lower than that of the traditional PU (polyurethane) material, so that the upper can greatly reduce its weight on the premise of ensuring necessary functions.

[0044] In addition, the surface of the upper can also be provided with a PP film (polypropylene film), and the PP film is covered on the outer layer of the upper by a specific fitting process, so that the surface presents a smooth state. The PP film itself has good chemical stability and smooth surface characteristics, which makes the upper more easily cleaned after staining stains. For example, when the upper contacts common stains such as dust and soil, the stains can be easily removed from the smooth surface of the PP film by simply wiping with a damp cloth or simple brushing, without complex cleaning steps, which is convenient and fast.

[0045] The shoe sole according to the present application has excellent shock absorption performance, can buffer the pressure of the foot, meet various movement requirements, and can give rapid energy feedback during movement by carrying a high elastic sheet, so as to improve the movement efficiency.

[0046] The vamp realizes the advantages of softness, air permeability, light weight, wear resistance and easy maintenance, and meets diversified demands of consumers for high-quality vamp.

[0047] The shoe combines the advantages of the shoe sole and the vamp, and meets the high quality demand of the children's comprehensive training shoes.
