[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Combined with the embodiments and Figure 1-4 A drainage, breathable and lightweight sole comprises an insole, an insole and an outsole 3 arranged in sequence from top to bottom, the insole and the outsole 3 are fixedly connected, the insole comprises a mesh cloth 11 fixed to the upper surface of a drainage layer 12, the drainage layer 12 is provided with a plurality of drainage through holes 121, the mesh wire upper surface 110 of the mesh cloth 11 is a concave-convex surface, and the mesh of the mesh cloth 11 is smaller than the drainage through holes 121;

[0022] The inner bottom is provided with a breathable mesh 2;

[0023] The lower surface of the large bottom 3 is concave to form at least one drainage groove 33. The bottom surface of the drainage groove 33 is provided with a plurality of water-permeable holes 31 communicating with the inner bottom, and the inner bottom surface 34 of the drainage groove is an arc surface.

[0024] The apertures of the water-permeable holes 31 and the drainage holes 121 are both larger than the apertures of the air-permeable mesh 2; and the water-permeable holes 31 and the drainage holes 121 are both perpendicular to the inner bottom.

[0025] The drainage holes 121 are honeycomb holes, and a plurality of anti-skid bosses 122 are arranged around the openings of the drainage holes 121 on the lower surface 120 of the drainage layer to enhance the friction between the insole and the sole and prevent the insole and the insole from slipping.

[0026] The concave-convex surface is formed by weaving or 3D printing. The mesh wire can be woven into knots or 3D printed on the upper surface to form a concave-convex surface, thereby enhancing the friction with the foot or socks. The concave-convex surface can be a wavy surface or a special-shaped curved surface, thereby ensuring skin-fitting comfort while increasing the friction surface.

[0027] The drainage layer 12 is integrally formed with a three-dimensional wrapping portion 123 for covering the midfoot and heel, and a plurality of cutouts 1231 are arranged on the periphery of the three-dimensional wrapping portion 123. The cutouts 1231 are staggered with the drainage holes 121 to facilitate the twisting of the sole during outdoor sports, and a vertical gap is left between the lowest point of the cutout 1231 and the bottom surface 120 of the drainage layer to ensure the support of the insole to the foot. The drainage layer is formed by EVA foaming, which is not easy to swell when immersed in water, so as to avoid the insole absorbing water and increasing weight to cause a burden on children.

[0028] Furthermore, the surface of the drainage layer is covered with a water-repellent coating to enhance the drainage efficiency of the insole and extend the life of the product.

[0029] Furthermore, the lower portion of the drainage layer is thickened to form a support portion to compensate for the support function of the midsole.

[0030] The drainage groove 33 is an annular groove, which forms a truncated cone on the lower surface of the large bottom 3. The surface of the truncated cone is concave to form a water-guiding annular groove 35 with a closed bottom surface. A water-guiding groove 32 is also provided on the lower surface of the large bottom 3 along the width direction, and one end of the water-guiding groove 32 is connected to the drainage groove 35.

[0031] Furthermore, the width of the water guide groove is 0.2-0.8 cm, which produces a pore water absorption effect relative to the annular groove; through the water guide annular groove and the water guide groove, drainage is guided in two directions on both sides of the annular groove, thereby enhancing the drainage and ventilation rate.

[0032] A pair of shoes comprises a water-draining, breathable and lightweight sole and an upper fixedly connected to the periphery of the sole.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
