DETAILED DESCRIPTION

[0031] The following will be described in detail in combination with the accompanying Figures 1-4 The present application will be further described in detail.

[0032] The embodiments of the present application disclose a light children's shoes. Referring to Figure 1 , the light children's shoes include a shoe sole body 1 and an upper body 2, and the upper body 2 is fixedly arranged on the shoe sole body 1.

[0033] Referring to Figure 1The upper body 2 is made of knitted mesh cloth to improve the lightness of the upper body 2. Meanwhile, the upper body 2 is provided with a plurality of air-permeable areas 21, and the air-permeable areas 21 are provided with a plurality of air-permeable holes 211, so as to improve the air permeability of the children's shoes and improve the comfort of the wearer.

[0034] With reference to Figure 1 and Figure 2 , the upper body 2 includes a first EVA insole 11, a second EVA insole 12 and a wear-resistant outsole 13 in sequence in a direction away from the upper body 2. The second EVA insole 12 is fixedly arranged on the wear-resistant outsole 13, and the wear-resistant outsole 13 is used to contact the ground. In this embodiment, the second EVA insole 12 is adhesively fixed to the wear-resistant outsole 13. The wear-resistant outsole 13 is made of wear-resistant rubber to improve the wear resistance of the children's shoes. The wear-resistant outsole 13 is provided with a plurality of anti-skid convex patterns on a side away from the second EVA insole 12 to improve the anti-skid performance of the children's shoes.

[0035] With reference to Figure 1 and Figure 2 , the first EVA insole 11 is fixedly connected to the second EVA insole 12, and the density of the first EVA insole 11 is greater than that of the second EVA insole 12. A plurality of support columns 111 are arranged on a side of the first EVA insole 11 close to the second EVA insole 12, and a plurality of accommodating grooves 121 for accommodating the support columns 111 are arranged on a side of the second EVA insole 12 close to the first EVA insole 11, so as to realize the fixed connection of the first EVA insole 11 and the second EVA insole 12. In this embodiment, the first EVA insole 11 and the second EVA insole 12 can be thermally formed in a mold. In another embodiment, the first EVA insole 11 and the second EVA insole 12 can be adhesively fixed.

[0036] The first EVA insole 11 and the second EVA insole 12 are both made of EVA material. The density of the EVA insole is related to the type and amount of foaming agent, the content of VA (vinyl acetate) and additives. In this embodiment, the density difference between the first EVA insole 11 and the second EVA insole 12 is realized by adjusting the VA content in the formula of the first EVA insole 11 and the second EVA insole 12. In this embodiment, the VA content of the second EVA insole 12 is relatively high, so that the second EVA insole 12 has a relatively low density. Because a higher VA content forms more voids in the insole, the mass per unit volume is reduced, and the density is relatively low. That is, the second EVA insole 12 has a relatively low density, so as to reduce the weight of the insole body 1, improve the lightness of the children's shoes and improve the comfort of the wearer.

[0037] Meanwhile, the first EVA midsole 11 has a larger density, so that the first EVA midsole 11 has a larger rigidity, so that the first EVA midsole 11 can provide a good supporting force for the wearer's foot. And the supporting column 111 of the first EVA midsole 11 is inserted into the accommodating groove 121 of the second EVA midsole 12, so that the supporting performance of the whole sole body 1 is further improved through the extended supporting column 111, and the comfort of the wearer is improved.

[0038] In summary: the first EVA midsole 11 has good supporting performance and provides support for the wearer's foot; meanwhile, the second EVA midsole 12 has a lower density, so that the overall quality of the sole body 1 can be reduced, the lightness of the children's shoes is improved, the wearing burden of the wearer is reduced, and the comfort of the wearer is improved.

[0039] Referring to Figure 1 and Figure 2 Meanwhile, the first EVA midsole 11 is provided with an arc-shaped protrusion 112 away from the second EVA midsole 12, and the arc-shaped protrusion 112 is arranged at the arch of the sole body 1. The arc-shaped protrusion 112 is used to support the arch area of the foot, so as to reduce the stretching of the arch area of the wearer and reduce the strain of the arch area of the wearer.

[0040] Embodiment 2

[0041] The difference between this embodiment 2 and embodiment 1 is:

[0042] Referring to Figure 3 , the area of the cross section of the supporting column 111 decreases along the direction away from the first EVA midsole 11; so as to improve the deformation ability of the supporting column 111. Thus, when the sole body 1 is stressed, the cooperative performance of the first EVA midsole 11 and the second EVA midsole 12 can be improved, so as to fully exert the elastic performance of the second EVA midsole 12.

[0043] Referring to Figure 3 , the sole body 1 further comprises a tensile-resistant wire 3, which is embedded in the first EVA midsole 11 and the second EVA midsole 12. The tensile-resistant wire 3 is used to connect the first EVA midsole 11 and the second EVA midsole 12, so as to improve the connection strength of the first EVA midsole 11 and the second EVA midsole 12. The tensile-resistant wire 3 is a metal wire, a tear-resistant strong latex wire or a synthetic fiber wire; in this embodiment, the tensile-resistant wire 3 is a metal wire. When the foaming materials of the first EVA midsole 11 and the second EVA midsole 12 are placed in layers in the mold, the tensile-resistant wire 3 can be placed in the foaming materials at the same time; so that after the foaming of the first EVA midsole 11 and the second EVA midsole 12 is completed, the tensile-resistant wire 3 is arranged in the first EVA midsole 11 and the second EVA midsole 12.

[0044] Embodiment 3

[0045] The difference between this embodiment 3 and embodiment 1 is that:

[0046] With reference to Figure 4 The sole body 1 further comprises a slow-rebound polyurethane midsole 4, which is fixedly arranged on the side of the first EVA midsole 11 away from the second EVA midsole 12, and is arranged in the shoe cavity of the upper body 2, and the upper body 2 is connected with the first EVA midsole 11. The slow-rebound polyurethane midsole 4 has good softness, deformation performance, and good slow-rebound performance; thus, when the wearer's foot is placed on the slow-rebound polyurethane midsole 4, the slow-rebound polyurethane midsole 4 can adapt to the shape of the wearer's foot, and provide personalized support, so as to improve the support effect of the sole body 1 on the wearer's foot. At the same time, the slow-rebound polyurethane midsole 4 is soft in texture, and can improve the comfort of the wearer's foot.

[0047] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
