[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 - Figure 4 This application provides a breathable shoe sole, including a first shoe sole 1 and a second shoe sole 2 fixedly connected. The first shoe sole 1 is placed on the top surface of the second shoe sole 2. The first shoe sole 1 is used to contact the user's foot, and the second shoe sole 2 is used to contact the ground. The first shoe sole 1 and the second shoe sole 2 are connected by adhesive or mechanical interlocking.

[0018] Furthermore, a plurality of ventilation holes 101 are formed through the first sole 1 along its thickness direction, and a plurality of air guide grooves 3 are formed on the bottom surface of the first sole 1 and / or the top surface of the second sole 2. The air guide grooves 3 extend toward the side of the sole and communicate with the outer edge, and the plurality of air guide grooves 3 and the plurality of ventilation holes 101 are correspondingly connected. Therefore, air can circulate in the air guide grooves 3 and ventilation holes 101.

[0019] Specifically, when the bottom surface of the first sole 1 and the top surface of the second sole 2 are attached, the guide groove 3 and the ventilation hole 101 together form an airflow channel, which connects the space above the first sole 1 and the outer edge of the sole. The space above the first sole 1 is the internal space of the shoe. Therefore, the airflow channel allows the air inside the shoe to exchange and circulate with the air outside, thus making the sole breathable and improving the breathability.

[0020] Among them, a number of ventilation holes 101 are distributed at intervals in various areas near the edge of the top surface of the first shoe sole 1, and a number of air guide grooves 3 are distributed at intervals along the edge contour of the shoe sole, so that the air in each area of ​​the shoe can be replaced by external air from various directions, thereby improving the air circulation efficiency.

[0021] Furthermore, at least one air channel 102 is formed by an inwardly recessed top surface of the first sole 1. The outer contour of the air channel 102 is the same as the edge contour of the first sole 1 but different in size. A vent 101 is formed inside the air channel 102, and the air channel 102 is connected to the airflow channel. The air channel 102 has a circulation loop structure, which allows for a wider range of air circulation.

[0022] In this embodiment, the air-guiding channel 102 includes at least two vertical segments extending along the length direction of the first sole 1. The top surface of the first sole 1 is recessed inward to form a plurality of connecting channels 103. The connecting channels 103 extend along the width direction of the first sole 1 and are used to connect all the vertical segments of the air-guiding channel 102. The connecting channels 103 and the air-guiding channel 102 have the same depth. When air enters the air-guiding channel 102 from the vent 101, the air can diffuse more quickly from the connecting channels 103 to every area above the first sole 1, and the air inside the first sole 1 can be expelled more quickly, improving breathability.

[0023] It is worth mentioning that the top surface of the first sole 1 is provided with a honeycomb-shaped diversion channel 104. The diversion channel 104 is connected to the air guide channel 102 and the connecting channel 103. The diversion channel 104 and the connecting channel 103 have the same effect, which can make the air diffuse and circulate faster. At the same time, the air guide channel 102, the connecting channel 103 and the diversion channel 104 can make a channel gap between the user's foot and the first sole 1, thereby avoiding the user's foot from being tightly attached to the sole and affecting the breathability.

[0024] In this design, lightweight holes 105 are provided in part of the honeycomb grid of the diversion channel 104, either penetrating or non-penetrating along the thickness direction of the first sole 1. When the lightweight holes 105 are through holes, they can be connected to the guide groove 3, which makes the sole lighter while also improving breathability.

[0025] It should be noted that the edge contour of the second sole 2 matches the edge contour of the first sole 1. The top surface of the second sole 2 is an inwardly concave arc surface, while the bottom surface of the first sole 1 is an outwardly convex arc surface. The top contour of the second sole 2 matches the bottom contour of the first sole 1. Therefore, the first sole 1 and the second sole 2 can fit perfectly together with flush edges, improving the overall aesthetics.

[0026] Furthermore, the second sole 2 has a hollow opening 201 in the middle area, and the bottom surface of the first sole 1 protrudes outward from the hollow opening 201 to form a positioning protrusion 106, the shape of which is adapted to the shape of the positioning protrusion 106 and the hollow opening 201. When the first sole 1 and the second sole 2 are assembled, they can be quickly positioned by the positioning protrusion 106 and the hollow opening 201, which speeds up the assembly efficiency. Moreover, the interference fit between the positioning protrusion 106 and the hollow opening 201 makes the assembled product more stable.

[0027] Among them, the hollow opening 201 can make the second sole 2 lighter, and the positioning protrusion 106 can improve the strength of the second sole 2 while positioning, so as to avoid the lack of support in the middle area.

[0028] It is worth mentioning that the side of the second sole 2 is provided with several drainage channels 202 corresponding to several guide channels 3. The drainage channels 202 are inclined along the thickness direction of the second sole 2. The top of the drainage channel 202 is connected to the guide channel 3, and the bottom of the drainage channel 202 is connected to the bottom edge of the second sole 2. When rainwater splashes onto the side of the sole, the drainage channels 202 can guide the rainwater to flow downward from the drainage channels 202, reducing the amount of rainwater entering the guide channels 3. Under the pressure of the user's foot, a small amount of water in the guide channels 3 can also be squeezed out into the drainage channels 202 and discharged.

[0029] In this embodiment, the sole has an anti-slip component, which includes a first anti-slip pattern 107 disposed on the surface of the positioning protrusion 106, and a second anti-slip pattern 203 disposed on the bottom surface of the second sole 2. The first anti-slip pattern 107 and the second anti-slip pattern 203 are striped or grid-like, and can be designed according to actual needs to increase friction with the ground, improve grip, and reduce the risk of slipping.

[0030] The working principle and usage process of this utility model are as follows: During use, when the user lifts their foot, the sole is not squeezed, and the port of the guide groove 3 on the side of the sole opens, so that the guide groove 3 and the ventilation hole 101 form an airflow channel, allowing the air inside the shoe to circulate and exchange with the air outside; when the user puts their foot down, the sole is squeezed, and the air inside the shoe is squeezed into the ventilation hole 101 from the air guide channel 102, the connecting channel 103, and the diversion channel 104, and is finally instantly discharged from the opening of the guide groove 3, making the sole more breathable, improving the breathability effect, and enhancing the user's comfort during use.
