Waterproof, air-permeable, skidproof and cushioning combined shoe sole with multilayered structure

Abstract

The invention relates to a waterproof, air-permeable, skidproof and cushioning combined shoe sole with multilayered structure, which is used for casual shoes, travel shoes, sports shoes, leather shoes and the like. The shoe sole consists of an outsole, a waterproof and air-permeable component and an air-permeable midsole arranged from bottom up. The outsole is provided with air-permeable sections at least at the position corresponding to the sole and / or heel of people; several bending segments protruding towards the top surface of the outsole are formed at the air-permeable sections of the outsole and are parallel with each other at interval; every two bending segments are connected by means of a plane part; the bending segments divides the outsole into a lower air storage space in communication with the lower surface of the outsole, and an upper air storage space in communication with the waterproof and air-permeable component; and the bending segment is provided with air-permeable holes capable of communicating the lower air storage space with the upper air storage space. The air-permeable holes are parallel to the surface of the outsole so that the shoe sole is skidproof and cushioning and effectively prevents foreign matters from piercing the waterproof and air-permeable component.

Description

technical field [0001] The present invention relates to a waterproof and breathable sole for but not limited to casual shoes, travel shoes, sports shoes, leather shoes and the like. Background technique [0002] With the development of society, people have higher and higher requirements for the comfort of shoes. The comfort of the shoe has a lot to do with whether the water vapor generated by perspiration in the shoe can properly penetrate outwards. Of course, this water vapor penetration cannot affect the waterproofness of the shoe. [0003] There are two main types of existing soles: one is a sole made of breathable natural leather material. Shoes made of this type of sole cannot ensure good water resistance in rainy or bad weather due to their permeability, and can easily absorb moisture; the other is a sole made of rubber material. This type of sole has poor air permeability, and the water vapor in the shoe cannot penetrate into the external environment. [0004] Ther...

AI Technical Summary

Problems solved by technology

However, there are still problems such as relatively complex structure, various processes, high cost, and difficult realization.

More importantly, the ventilation holes of these soles are generally exposed on the sole surface, and are easily pierced by sharp objects on the ground so that the soles and even the waterproof and breathable membrane are damaged; on the other hand, the setting of the ventilation holes of these soles also reduces The contact area between the sole and the ground is reduced, the structural strength of the sole is reduced, and the service life of the shoe is shortened
