Breathable waterproof soles and shoes

Abstract

The invention provides breathable waterproof soles and breathable waterproof shoes. Each sole comprises a tread base, an upward protuberant flange is arranged at the periphery of the tread base, the flange is provided with air holes which penetrate through the inner side face and the outer side face of the flange, the air holes can be sealed by at least one layer of waterproof breathable cloth through which air can pass; the top of the flange is also provided with an eave extending toward the periphery of the tread base, the air holes are arranged below the eave and close to the eave; and theinterior of the tread base is provided with multiple cavities separated by barriers, the upper ends of the cavities are open, the lower ends of the cavities are closed, and distance is reserved between the top surfaces of the cavities and the lower edges of inner opening of the air holes. The breathable waterproof soles provided by the invention have simple structure and low manufacturing cost, are waterproof and dustproof, can prevent from being punctured by foreign matters, have long-lasting air permeability, are durable in use, can realize breathing and ventilation of shoes, are especiallysuitable to be used for producing leather casual shoes and have good comfortableness.

Description

technical field [0001] The invention belongs to the field of shoemaking, and in particular relates to a sole and a shoe capable of both air permeability and waterproof. Background technique [0002] In order to adapt to the needs of users, the design of footwear has been continuously developed to find and determine the technical solutions that can provide people with the best comfort. As we all know, the comfort of shoes not only depends on the soles that conform to human anatomy, but also depends 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 the growth of bacteria. However, this water vapor penetration will inevitably affect the waterproofness of shoes, so people try to design vamps or soles that can penetrate water vapor. [0003] Most of the foot sweat occurs between the soles of the feet and the soles. The sweat here cannot evaporate and will accumulate on the insoles and ...

AI Technical Summary

Problems solved by technology

However, although genuine leather is breathable, it also absorbs water, and the cushioning performance of thinner leather soles is not good, and cushioning devices cannot be installed. Therefore, most modern shoes are made of resin soles. We need to study the breathable structure of resin soles

[0004] Both WO2004028284A1 and CN1993065A disclose a breathable and waterproof sole. The sole of this sole is divided into multiple layers, and a board with holes is installed on the sole. As an assembly, there are perforated substrates, breathable waterproof membranes, felts, protective nets, etc. Although the soles of this structure have certain breathable and waterproof functions, they have the following inevitable defects: the one is the complex structure. Install a board with a multi-layer structure on the bottom of the board. The layers of the board need to be pre-assembled and bonded, the manufacturing process is complicated, and the cost is high; the second is that the breathable waterproof membrane is a thin film, which lacks sufficient structural performance The modulus of elasticity of the sole is also different. In fact, after the film is continuously exerted by the foot, even if no particularly sharp object penetrates into the hole of the substrate, it is easy to be torn and damaged, and the holes on these inserts For the up and down direction, directly facing the ground, close to the ground, dirt, dust and gravel will wedge into the holes, blocking these holes and restricting air permeability; the third is that it has pores directly facing the ground, and the waterproof performance of the sole is not good
