A waterproof breathable sole

Abstract

The invention relates to a shoe sole, which provides a waterproof and breathable shoe sole with simple structure, convenient manufacture, and effective ventilation and waterproof effects. A ventilation groove is provided, and the ventilation groove is a ring-shaped threaded groove formed by turning and winding from the outside to the inside. Air notch; the midsole is provided with air holes that run through its upper and lower surfaces, the air holes are located above the inner ends of the ring-shaped thread grooves, and the air holes and the inner ends of the ring-shaped thread grooves The ends are connected.

Description

technical field [0001] The invention relates to a shoe sole, in particular to a waterproof and breathable shoe sole. Background technique [0002] Shoes are an indispensable daily necessities in people's daily life. The comfort of shoes depends not only on the soles conforming to human anatomy, but also on whether the shoes can discharge the water vapor generated by perspiration in the shoes, so as to avoid the dampness and heat in the shoes, and bacteria breed. Most of the foot sweat in the shoes occurs between the soles of the feet and the soles. The sweat here is difficult to evaporate, and will gather on the insoles and insoles that the feet step on, especially resin soles. This problem is particularly important. Penetration through the sole is completely blocked, in order to solve this technical problem, [0003] In the prior art, a method of setting breathable waterproof cloth and vent holes in the sole is adopted to achieve breathable and waterproof effect.

AI Technical Summary

Problems solved by technology

[0003] In the prior art, a method of setting breathable waterproof cloth and vent holes in the sole is adopted to achieve breathable and waterproof effect. The vent holes communicate the inner space of the sole with the outside world, and the breathable waterproof cloth is used to block water and pass air, so that the inside of the shoe The hot and humid air leaks out, and the fresh air from the outside enters to realize ventilation, but the breathable waterproof sole has the following defects: 1. The inner space of the sole is narrow and small, and the space capacity for accommodating the hot and humid air is limited. If the air in the shoe cannot be discharged in time, There may be a problem of backflow of hot air; 2. The installation structure of the breathable waterproof cloth is not ideal, the reliability is poor, it is easy to fall off and shift, and it cannot guarantee that it can still filter water after wearing it for a long time, which will affect the waterproof performance; 3. The structure is complex, high manufacturing cost
