Benefits of technology
The present invention is a functional shoe with cushioning and air circulation functions. It has a foldable resilient member that improves impact absorption and provides good landing comfort. The shoe can be actively air-circulated to improve air circulation and maintain a comfortable state, increasing wearing comfort. The foldable resilient member has a simple structure and high durability, improving the production efficiency of the shoe. Natural rolling movement and discharge of far-infrared light or anion from the insole enhance effective walking and maximize wearing comfort.
Problems solved by technology
However, when elastic material is used, manufacturing cost is increased, and elasticity of the elastic material is gradually reduced as time elapses.
In addition, since the method of installing coil springs in the heel is limited to a resilient distance of the spring, a sufficient cushioning function cannot be expected and a structure thereof becomes complex, making it difficult to manufacture the shoe.
However, since this technique is a passive method, air circulation efficiency is largely decreased.

A functional shoe pertains to a cushioning function and an air circulation function, which integrally performs the cushioning function and the air circulation function. The functional shoe includes: an insole (110) and a midsole (120) having a tunnel portion (122). The tunnel portion (122) has a lower surface (122a) and an upper surface (122b) having a predetermined angle (α) with the lower surface (122a); an outsole (130) having an anti-slip tread (132); a foldable resilient member (140) having a support portion (142) for supporting the lower surface (122a) of the tunnel portion (122), and a rotating portion (144). The rotating portion (144) is resiliently folded by the load being applied thereto; a sealing member (150); and an air channel (160) having one end communicated to the closed tunnel (122) and the other end located at the front end of the insole (110).
Description
TECHNICAL FIELD[0001]The present invention relates to a shoe, and more particularly, to a functional shoe having cushioning and air circulation functions capable of providing good landing comfort and pleasant wearing comfort by simultaneously performing the cushioning and air circulation functions.BACKGROUND ART[0002]In shoes, one of daily necessities, as the standard of living is increased, various functional shoes based on an ergonomic design beyond a simple function for protecting the feet are being developed. Major functions of the functional shoes may include a cushioning function, an air circulation function, and so on.[0003]The cushioning function is provided to absorb impact applied to a heel of a shoe that first comes in contact with the ground surface upon walking, improving landing comfort. That is, the impact applied from the heel through the cushioning function is attenuated to reduce fatigue felt by a walker. As a conventional art for the cushioning function, a method ...
