[0032] Embodiment 1:

[0033] This embodiment provides a breathable sole, comprising:

[0034] An insole 1, wherein the insole 1 is provided with a plurality of first ventilation holes 4 at the sole of the foot, and a first notch 5 is provided at the bottom of the insole 1 at the heel;

[0035] An outer sole 2, wherein the outer sole 2 is bonded to the inner sole 1 at the sole, a receiving cavity 6 is provided on the outer sole 2 at the sole, and a second notch 7 is provided on the outer sole 2 at the heel;

[0036] A ventilation assembly 3 is disposed between the insole 1 and the outsole 2, and includes a U-shaped ventilation bag 31 and two ventilation hoses 32 connected to the ends of the U-shaped ventilation bag 31;

[0037] The U-shaped ventilation bag 31 is arranged between the first notch 5 and the second notch 7 , the ventilation hose 32 is arranged in the accommodating cavity 6 , and a plurality of second ventilation holes 8 are provided on the ventilation hose 32 , which are connected with the first ventilation holes 4 through the accommodating cavity 6 .

[0038] In the present technical solution, the insole 1 and the outsole 2 are not connected on the periphery at the heel, and are provided with a first notch 5 and a second notch 7, thereby forming a space to accommodate a U-shaped air bag 31. The U-shaped air bag 31 is a hollow elastomer. The U-shaped air bag 31 is arranged along the outer periphery of the insole 1 and the outsole 2, with the two ends facing the direction of the sole, and the outer periphery of the U-shaped air bag 31 is glued and connected to the periphery of the insole 1 and the outsole 2 to prevent ground water from seeping into the gap between the U-shaped air bag 31 and the insole 1 and the outsole 2. Two ventilation hoses 32 are connected to the ends of the U-shaped air bag 31. The ventilation hoses 32 can be soft rubber hoses to facilitate bending of the foot when walking.

[0039] After the user puts on the sole for exercise, when the foot steps on the ground, the heel of the insole 1 presses the U-shaped air bag 31 downward, and the U-shaped air bag 31 is compressed and deformed by the downward gravity. The space formed by the first notch 5 and the second notch 7 is used to allow the heel of the insole 1 to have space to move up and down to meet the deformation condition of the U-shaped air bag 31. The gas in the U-shaped air bag 31 is squeezed into the ventilation hose 32, and the second air hole 8 is connected with the first air hole 4 through the accommodating cavity 6 to discharge the gas out of the sole, thereby taking the moisture and odor in the sole out of the sole. At this time, the U-shaped air bag 31 is compressed and deformed. 1 is in a negative pressure state; when the foot leaves the ground, the heel of the insole 1 is reset, and the U-shaped air bag 31 loses the downward gravity and returns to its original shape. At this time, the gas outside the sole passes through the first air hole 4, the accommodating cavity 6, the second air hole and the air hose 32 in sequence and enters the U-shaped air bag 31; therefore, every time the user takes a step, a ventilation process is completed to achieve the function of gas circulation in the sole, and the moisture and odor of the sole are taken out of the sole, thereby achieving a ventilation effect. At the same time, the U-shaped air bag 31 can make more gas circulate in the sole, increasing the gas circulation amount.

[0040] The bottom of the outer sole 2 is also bonded with an anti-skid member 19, which can be made of wear-resistant and stretch-resistant EVA material. The anti-skid member 19 is provided with a plurality of anti-skid grooves to prevent the sole from slipping and the user from slipping.

[0041] Embodiment 2:

[0042] This embodiment provides a breathable sole, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0043] A plurality of reinforcing ribs 9 are arranged in the accommodating cavity 6 , and the upper ends of the reinforcing ribs 9 are in contact with the bottom of the inner bottom 1 . The reinforcing ribs 9 are provided with two slots 10 , and the ventilation hose 32 is clipped on the slots 10 .

[0044] In the present technical solution, a number of reinforcing ribs 9 are used to increase the structural strength of the outsole 2 to withstand forces from the lateral or front-to-back directions. At the same time, the upper ends of the reinforcing ribs 9 are in contact with the bottom of the insole 1 to support the insole 1. Two card slots 10 are provided on the reinforcing ribs 9. The height of the card slots 10 is greater than or equal to the outer diameter of the ventilation hose 32. The ventilation hose 32 is connected to the card slots 10 to prevent the ventilation hose 32 from being squeezed and deformed.

[0045] Embodiment 3:

[0046] This embodiment provides a breathable sole, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0047] The second air vent 8 is connected to the first air vent 4 via a ventilation groove 11 formed between adjacent reinforcing ribs 9 .

[0048] In the present technical solution, the second air holes 8 are symmetrically arranged on the ventilation hose 32, and the second air holes 8 face the ventilation grooves 11. The upper ends of the reinforcing ribs 9 are in contact with the bottom of the insole 1. When the gas circulates in the sole, the gas passes through the first air holes 4, the ventilation grooves 11 and the second air holes 8. The gas passes through each ventilation groove 11, so that the gas circulates evenly in the sole.

[0049] Embodiment 4:

[0050] This embodiment provides a breathable sole, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0052] In the present technical solution, the shock-absorbing airbag 13 is a sealed hollow airbag with elasticity, which can support the heel and provide shock-absorbing and cushioning effect on the ankles and knees. The shock-absorbing airbag 13 rebounds under the downward gravity to reduce the impact of the user's own gravity on the ankles and knees. The upper end of the shock-absorbing airbag 13 is an arc-shaped surface, which can increase the degree of deformation and improve the rebound performance, while preventing the shock-absorbing airbag 13 from affecting the compression degree of the U-shaped air bag 31.

[0053] In addition, the shock-absorbing airbag 13 and the U-shaped air bag 31 are connected by a connecting piece 12. The shock-absorbing airbag 13, the U-shaped air bag 31 and the connecting piece 12 can be made of thermoplastic TPU material and can be integrally formed by a blow molding process. The shock-absorbing airbag 13, the U-shaped air bag 31 and the connecting piece 12 are divided into an upper and lower part, which are then connected by ultrasound to form the shock-absorbing airbag 13 and the U-shaped air bag 31, thereby enhancing the stability of the shock-absorbing airbag 13, reducing the processing flow, and facilitating the installation of the sole.
