[0002] The main purpose of the sole is to protect the feet and prevent them from being stabbed by sharp objects or bumped by hard objects. The existing soles can also be designed with different functions according to needs. For example, when people walk or exercise, their feet are prone to sweating, especially the soles of the feet. If the feet are in a hot and humid environment for a long time, they will feel uncomfortable and easily breed bacteria, which will cause the feet to emit odor. To address this situation, various soles with breathable functions have appeared on the market.
[0003] In the prior art, a shoe sole with a breathable function usually has a plurality of air holes on the inner sole to achieve a breathable effect. However, this method has a slow heat dissipation and ventilation speed, and the gas in the shoe cannot be discharged in time. In addition, the soles of the feet are most prone to sweating, and this method has limited ventilation effect on the soles of the feet, so the ventilation effect is poor. Utility Model Content
[0004] The purpose of the utility model is to provide a waterproof and breathable sole in view of the above-mentioned technical problems. When the sole of the shoe is subjected to pressure from the sole of the foot, a plurality of elastic convex particles undergo elastic deformation, so that the gas passes through the breathable groove, the first through hole and the waterproof breathable membrane from the bottom of the sole, thereby allowing the gas to circulate in the sole to achieve the effect of ventilation and dehumidification.
[0005] In view of this, the utility model provides a waterproof and breathable sole, comprising an inner sole, a midsole and an outer sole arranged in sequence from top to bottom;
[0006] The top of the midsole is provided with a waterproof breathable membrane at the sole, the bottom of the midsole is provided with a receiving groove at the sole, a plurality of elastic convex particles that interfere with the outsole are provided in the receiving groove, a first through hole that penetrates the midsole is provided on the elastic convex particles, a ring groove is provided at the bottom of the outsole at the sole, a plurality of breathable grooves connected with the ring groove are provided at the top of the outsole at the sole, and the breathable grooves are also connected to a plurality of first through holes.

[0009] In the above solution, further, the waterproof and breathable membrane is made of expanded polytetrafluoroethylene.
[0010] In the above solution, further, an elastic shock absorbing part is provided on the midsole at the heel.
[0011] In the above scheme, further, an elliptical shock absorbing cylinder is laterally arranged in the elastic shock absorbing part.
[0012] In the above scheme, further, two arc-shaped support members are symmetrically inserted in the elliptical shock-absorbing cylinder, the arc-shaped support members are connected to the inner circumferential wall of the elliptical shock-absorbing cylinder, and the arc surfaces of the two arc-shaped support members are in conflict with each other.
[0013] In the above solution, further, the material of the midsole is EVA material using a foaming process.
[0014] The beneficial effects of the utility model are:
[0015] 1. The gas circulates in the sole, discharges the water vapor generated by sweating on the sole and dissipates the heat, achieving the effect of ventilation and dehumidification of the sole. The waterproof and breathable membrane is breathable and can prevent ground water from entering the sole;
[0016] 2. The structure of the ring groove connecting the ventilation groove can prevent the mud and sand on the ground from blocking the ventilation channel, or prevent sharp objects from passing through the ventilation channel and piercing the soles of the feet;
[0017] 3. Some elastic convex particles undergo elastic deformation and generate rebound force, which can provide shock absorption and buffering effect on the sole of the foot, so as to protect the foot and make walking and exercise more comfortable and labor-saving;
[0018] 4. After the elliptical shock-absorbing cylinder undergoes elastic deformation, it generates a rebound force on the heel, making walking or exercising more labor-saving. The two arc-shaped support members are squeezed by the elliptical shock-absorbing cylinder, generating an elastic repulsive force on the elliptical shock-absorbing cylinder, further improving the rebound force of the elliptical shock-absorbing cylinder.

[0031] Embodiment 1:
[0032] This embodiment provides a waterproof and breathable sole, comprising an insole 2, a midsole 3 and an outsole 4 arranged in sequence from top to bottom;
[0033] Among them, a waterproof and breathable membrane 5 is provided at the top of the midsole 3 at the sole, a receiving groove 6 is provided at the bottom of the midsole 3 at the sole, a plurality of elastic convex particles 7 that interfere with the outsole 4 are provided in the receiving groove 6, and a first through hole 8 that penetrates the midsole 3 is provided on the elastic convex particles 7. An annular groove 9 is provided at the bottom of the outsole 4 at the sole, and a plurality of breathable grooves 10 connected with the annular groove 9 are provided at the top of the outsole 4 at the sole, and the breathable grooves 10 are also connected to a plurality of first through holes 8.
[0034] In this technical solution, the outsole 4 is glued and connected to the bottom of the midsole 3 . The midsole 3 can be made of breathable Hypoly foam. The outsole 4 can be made of rubber. The waterproof and breathable membrane 5 is glued and connected to the midsole 3 .
[0035] The two ends of the ventilation groove 10 extend to the annular groove 9 and are connected with the annular groove 9. During walking or exercise, air enters the ventilation groove 10 through the annular groove 9 at the bottom of the outer sole 4, and then enters the first through hole 8 on the elastic convex particle 7 connected with the ventilation groove 10, and then enters the sole through the waterproof breathable membrane 5 and the fine holes on the insole 2; the gas in the sole is discharged out of the shoe through the insole 2, the waterproof breathable membrane 5, the first through hole 8, the ventilation groove 10 and the annular groove 9 in sequence, so the insole 2, the waterproof breathable membrane 5, the first through hole 8, the ventilation groove 10 and the annular groove 9 generate a ventilation channel on the sole, and the ventilation channel completes the circulation of gas in the sole, and at the same time, the water vapor generated by sweating at the sole is discharged and the heat is dissipated, so that the foot and the sole are dry, so as to achieve the ventilation and dehumidification effect of the sole.
[0036] Among them, the waterproof and breathable membrane 5 can be a material with both waterproof and breathable properties, which allows gas and water vapor to pass through and is waterproof. When there is water accumulation on the bottom surface and the sole steps into the accumulated water, the waterproof and breathable membrane 5 is used to isolate the water and prevent water from entering the sole through the annular groove 9, the breathable groove 10 and the first through hole 8. Therefore, the sole can achieve the effect of ventilation and dehumidification while preventing water from entering the sole.
[0037] The structure of the annular groove 9 being connected to the ventilation groove 10 can not only be used to allow gas to circulate, but also prevent mud and sand on the ground from blocking the ventilation channel, or prevent sharp objects from passing through the ventilation channel and piercing the soles of the feet.
[0038] When the foot lands and starts to move, the sole of the foot generates pressure on the sole of the shoe, causing the plurality of elastic convex particles 7 in the accommodating groove 6 to undergo elastic deformation. The moment the sole leaves the ground, the elastic convex particles 7 recover their deformation and generate rebound force, which can have a shock-absorbing and buffering effect on the sole of the foot, thereby protecting the foot and making walking and exercising more comfortable and labor-saving.
