Footwear sole with unidirectional air-circulation bladder, mold, and manufacturing method therefor
By incorporating air pockets and one-way channels in the heel area of the sole, the shoe utilizes the compression and expansion of the foot during walking to achieve air exchange between the inside and outside of the shoe. This solves the problem of poor breathability in traditional shoes, improves comfort, and reduces costs.

AI Technical Summary
Technical Problem
Traditional shoes have poor breathability, which leads to moisture buildup inside the shoe and affects comfort.
Method used
A one-way air circulation airbag sole is designed. An airbag groove is set in the heel of the sole, and an airbag cavity is formed by the airbag cover and the airbag groove. Combined with the first and second one-way flow channels and air tubes, the one-way flow of gas is realized. The air exchange between the inside and outside of the shoe is realized by the compression and expansion of the foot during walking.
Benefits of technology
It effectively improves the breathability and comfort of the shoe, reduces manufacturing costs, shortens the production cycle, and increases production efficiency.
