The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0023] Example 1: Figure 1-4 , including a covering layer, the covering layer includes an insole bottom 100 and an insole surface 120, the insole bottom 100 and the insole surface 120 are clamped and installed with a first insole core 200 and a second insole core 300, the first insole core 200 and the second insole core 300 are arranged in an up-and-down manner, the top sole of the second insole core 300 is evenly provided with a first protruding block 310, and a gap groove 320 is provided between adjacent first protruding blocks 310, the sole of the foot of the outer wall of the bottom surface of the second insole core 300 is evenly provided with a second protruding block 350, and a truncated groove 351 is opened between adjacent second protruding blocks 350, the top midfoot part of the second insole core 300 is evenly provided with a circular protrusion 340, the second insole core 300 is provided with a teardrop-shaped protrusion 330 at the heel, the second insole core 300 is provided with a limiting groove 360 ​​around the bottom of the second insole core 300, and the surface of the first insole core 200 is evenly provided with a through ventilation hole 220.

[0024] The specific usage scenario of this embodiment is as follows: a cavity structure is formed inside the breathable insole by arranging a covering layer and a first insole core 200 and a second insole core 300 to form a combination thereof, so that the interior of the breathable insole can always maintain a fluffy feeling, and air is retained inside, so that when the air columns inside the first insole core 200 and the second insole core 300 are squeezed during the movement of the user's feet, the internal air can flow, accelerate the evaporation of internal sweat, and play a certain role in energy absorption and buffering, thereby improving the impact resistance of the sole; a first protruding block 310, a second protruding block 350, a circular protruding block 340 and a teardrop-shaped protruding block 330 are arranged on the surface of the second insole core 300 for use in combination, and protruding blocks of corresponding shapes are designed on the top and bottom surfaces of the second insole core 300 according to the ergonomics of the sole of the human body to form a concave inner portion. The embedded part and the concave embedded part are used to fix the size of the foot core and maintain stability. At the same time, the concave conical structure at the bottom can allow more air to circulate inside, thereby facilitating the improvement of the support effect on the sole of the foot and the sports buffering effect. The ventilation holes 220 are provided to provide ventilation and perspiration between the top and bottom of the first insole core 200. The teardrop-shaped protrusions 330 are provided to support and limit the heel. The design of the first protrusion block 310 and the second protrusion block 350 is based on the characteristics of the first layer of cowhide. The cowhide material will become shiny and slippery after long-term wearing. The wavy pattern can increase friction. The soft and high-rebound design will not cause any discomfort to the footsteps, thereby improving the anti-slip effect and the comfort level. The first protrusion block 310 and the second protrusion block 350 can be set to an S shape or a dot matrix shape.

[0025] Example 2: Figure 1 and Figure 2 The insole bottom 100 and the insole surface 120 are made of top-layer cowhide. A first covering groove 110 is stamped on the surface of the insole bottom 100, and a second covering groove 130 is stamped on the surface of the insole surface 120. The first covering groove 110 and the second covering groove 130 are used to clamp and fix the first insole core 200 and the second insole core 300.

[0026] The specific usage scenario of this embodiment is: by providing an insole bottom 100 and an insole surface 120 for covering the first insole core 200 and the second insole core 300, the breathable insole can be used in combination. The material of the insole bottom 100 and the insole surface 120 can be selected from top-layer cowhide or top-layer sheepskin according to usage needs or the supply of raw materials. There are fine pores distributed on the surface of the insole bottom 100 and the insole surface 120, thereby enhancing the air permeability of the surface of the insole bottom 100 and the insole surface 120, so that sweat can penetrate into the first insole core 200 and the second insole core 300 through the fine pores on the surface of the insole bottom 100 and the insole surface 120, so that the entire breathable insole can more effectively promote ventilation and sweat discharge, thereby improving the comfort of using the breathable insole.

[0027] Example 3: Figure 5 and Figure 6 The top surface of the first insole core 200 is evenly provided with countersunk holes 210, the air vent 220 is provided at the center of the inner wall of the countersunk hole 210, the bottom end of the air vent 220 is provided with a conical protrusion 230, the bottom end of the air vent 220 is provided with a conical structure, the bottom outer wall of the first insole core 200 is evenly provided with polygonal grooves 240, the polygonal grooves 240 are evenly distributed around the air vent 220, and the material of the first insole core 200 is elastic cotton.

[0028] The specific usage scenario of this embodiment is: the air hole 220 and the inside of the first insole core 200 form a small space for air circulation. The polygonal groove 240 is provided to increase the cavity volume at the bottom of the first insole core 200, so as to form a larger air storage space inside the breathable insole, thereby improving the comfort of the sole of the foot. The first insole core 200 is made of high-density stretch cotton, which has a good shock-absorbing effect, is convenient for improving comfort, has obvious rebound, and is highly breathable. It can reduce the impact of steps and is not easy to deform after long-term wear.

[0029] The working principle of the utility model is as follows: when using, a technician in this field forms an insole core structure by stacking and combining the first insole core 200 and the second insole core 300, then covers the insole bottom 100 in the coating layer on the bottom of the first insole core 200, covers the insole surface 120 on the top of the second insole core 300, and then sews the insole bottom 100 and the insole surface 120 to form the overall structure of the breathable insole. When using, a breathable insole of corresponding size is selected, and the breathable insole is inserted and installed in the sole for use.

[0030] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
