Abstract

The invention discloses a breathable shoe sole. The breathable shoe sole solves problems that in the prior art, the breathable effect is poor, blockage and damage are prone to occurring due to complex arrangement of pipe holes, manufacturing cost is high, and comfort and durability are poor. The breathable shoe sole comprises a breathable middle sole provided with a breathable upper sole on the upper side, and is characterized in that a wear-resistant lower sole is arranged on a lower side of the breathable middle sole; a transition air bag cavity is formed in a front foot sole end of the breathable shoe insole, and foot sole front air inlet holes are formed in the upper side of the transition air bag cavity; flat one-way valves are arranged on two sides of the transition air bag cavity respectively, and ends of the flat one-way valves are connected with half sole side exhaust holes; a columnar one-way valve is arranged in a heel end of the breathable shoe insole, and two ends of the columnar one-way valve are connected with a foot sole heel portion air inlet hole and a heel portion side upper exhaust hole respectively. The reathable shoe sole is reasonable in design, compact in structure, capable of achieving one-way smooth flowing of fluid inside and outside the shoe, capable of rapidly draining moisture and water on the shoe sole, capable of improving the damp and hot closed environment in the shoe and capable of improving the comfort of the sole of the foot, flexible in self-adaptability and high in practicability.

Description

technical field

[0001] The invention belongs to the technical field of footwear manufacturing, and in particular relates to a unidirectional and smooth flow of fluid inside and outside the shoe, which can quickly drain the moisture and water from the sole, effectively improve the damp, hot and stuffy environment inside the shoe, and improve the comfort of the bottom of the foot. Feeling, flexible adaptability, practical and breathable sole. Background technique

[0002] The drainage and air permeability of shoes is one of the important indicators to measure their quality; at present, the technical method to realize the performance of this indicator mainly relies on the scheme of opening holes in the foam cavity of the sole or the upper part of the shoe chamber. Although this traditional method is simple and easy to manufacture, the opening of the holes will inevitably affect the comfort of the feet, and the overall ventilation effect is not ideal, and the actual use effect i...

Embodiment Construction

[0032] according to Figure 1-16 The specific structure of the present invention will be described in detail. The breathable sole includes a breathable shoe midsole 30, the upper side of the breathable shoe midsole 30 is provided with a breathable shoe upper bottom 32 with good permeability for covering the air inlet 4 at the front of the sole and the air inlet 6 at the heel of the foot; The lower side of the breathable shoe midsole 30 is provided with a wear-resistant shoe bottom 31 for contacting with the ground. The breathable midsole 30 is composed of the midsole main body 1 and the surrounding additives, and the filling part of the midsole main body 1 can be made of a material that is soft, elastic, and has a large compression space (for example: secondary foam PHYLON, PU, ​​etc.). The interior of the forefoot end 2 of the midsole main body 1 is provided with a transitional airbag cavity 8, and several groups of air intake holes 4 at the front of the sole are provided o...
