[0002] Shoes are daily items consisting of uppers, insoles, soles and heels, used to protect the human foot. Shoes have a certain degree of water vapor permeability in the sole and upper areas, also known as breathability. During outdoor sports, the feet produce a lot of sweat, which is difficult to evaporate quickly. Long-term sweat soaking can easily lead to various foot diseases. The breathability of shoes can enhance the air circulation inside the shoe cavity, enhance the circulation of gas inside the shoe cavity and fresh air outside, and improve the internal environment of the shoe.

[0003] The soles of existing shoes are mostly made of waterproof materials such as rubber or rubber-like plastics. Such soles have the disadvantage that sweat accumulates in the sole area. Utility Model Content

[0007] Preferably, the shock-absorbing layer is composed of a plurality of crystal structures, and the crystal structure is a polyhedral porous regular structure.

[0008] Preferably, the shock-absorbing layer and the curved sheet are integrally formed.

[0009] Preferably, the shock-absorbing layer and the curved sheet are formed by 3D printing.

[0018] 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 the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] like Figure 1-4 As shown, in one embodiment, a sweat-proof and breathable sole is proposed, which includes a plurality of curved sheets 1, and the side edges of the plurality of curved sheets 1 are overlapped in sequence to form the sweat-proof and breathable sole; a plurality of ventilation holes 2 are provided at the overlapping portions of the curved sheets 1.

[0020] In this embodiment, Figure 1-4 The overall structure diagram of the sweat-proof and breathable shoes is provided, but the focus of this embodiment is on the sole, and the view of the overall shoe is provided for ease of understanding. The shape of the curved sheet 1 of the sole described in this embodiment is a streamlined sheet, and the sides of the sheets overlap each other, and are assembled from left to right to form the sole. The "overlap" described in this embodiment does not mean that the upper and lower sides are completely overlapped, but that the sides of two adjacent curved sheets 1 are overlapped with each other, and the overlapping width size can be designed according to actual needs. The air vents 2 are arranged at this stacking position. When a person walks, air flow is more likely to enter the inside of the shoe along the air vents 2, and the high air permeability of the sole prevents sweat from accumulating in the sole.

[0021] Preferably, the curved sheet 1 is provided with a plurality of guide fins 3 , and two adjacent curved sheets 1 overlap on the guide fins 3 to form the air vents 2 .

[0022] In this preferred embodiment, a plurality of guide fins 3 are arranged in parallel on the inner side of the curved sheet 1. Two adjacent curved sheets 1 and two adjacent guide fins 3 form an air hole 2, which plays a role of ventilation. The guide fins 3 are parallel to each other and extend to the rear of the shoe, which plays a role of guiding air. The direction of the air hole 2 is from left to right, along the direction of the shoe tip. When a person walks or runs, the foot moves forward, and the airflow enters the inside of the shoe along the air hole 2, and takes away the heat and water vapor inside the shoe under the guidance of the guide fins 3.

[0023] Preferably, a plurality of hollow shock-absorbing layers 4 are arranged above the curved sheet 1. The shock-absorbing layer 4 is composed of a plurality of crystal structures, and the crystal structure is a polyhedral porous regular structure.

[0024] In this preferred embodiment, the shock-absorbing layer 4 is different from a general insole. It is evenly arranged above the curved sheet 1. The shock-absorbing layer 4 is provided with several layers, and each layer is provided with many hollow through holes, which are staggered with each other. The several shock-absorbing layers 4 arranged on the sole can play the role of shock absorption and buffering, and the hollow design on the shock-absorbing layer 4 cooperates with the air-permeable holes 2 to achieve a ventilation effect and prevent sweat from accumulating on the sole. The crystal structure is a continuous grid structure composed of a plurality of periodically arranged polygonal cubes. The polygonal cube grid can be a three-dimensional shape of different sizes, and its characteristic is that it can form a three-dimensional continuum structure with each other, such as a regular tetrahedron structure, a cube structure or a honeycomb structure, etc. The three-dimensional shape of the polyhedron is filled in the sole of the sports shoe, which can provide cushioning for the sports shoe through structural deformation and improve the air permeability. After the crystal structure is compressed and deformed, the ability to recover the deformation is strong, which can provide a certain resilience for the sports shoe. In addition, the shock-absorbing layer 4 raises the sole, and the porous structure of the crystal structure is orderly interlaced with each other, making it difficult for water on the ground to directly enter the sole through the air holes 2, thereby keeping the interior of the shoe breathable and dry.

[0025] Preferably, the shock absorbing layer 4 is integrally formed with the curved sheet 1. The shock absorbing layer 4 and the curved sheet 1 are formed by 3D printing. The raw material of the 3D printing is nylon or TPU powder.

[0026] In this preferred solution, since the shape of the breathable shoe in this embodiment is relatively unique, it is easier to produce by using the integrated molding technology. The shock-absorbing layer 4 is integrally molded with the entire breathable shoe by using the 3D printing technology, thereby reducing unnecessary industrial production processes.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
