Structure of shoe sole having superior ventilation function and double- landing function

Abstract

A shoe sole according to an aspect to the invention has ventilation function and has a double-landing function. The shoe sole includes a main groove, and sole including a pressure pad of a flat shape and connection portion. The main groove is formed on a bottom surface at a heel area and communicates with a ventilation groove supplying air into an inside of a shoe to supply the air into the inside of the shoe. The pressure pad convexly protrudes toward the ground at an area corresponding to the main groove. The connection portion connects the pressure pad and the sole. The shoe sole has a double-landing process. In the double-landing process, a bottom surface of the pressure pad is in contact with the ground and is introduced into the groove, and then, the bottom surface of the sole is in contact with the ground. The connection portion is thinner than the pressure pad so that the pressure pad is easily introduced when landing.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims foreign priority of Korean Patent Application No. 10-2011-0055194, filed on Jun. 8, 2011, which is incorporated by reference in its entirety into this application.TECHNICAL FIELD[0002]The invention relates to a shoe sole having superior ventilation function and having a double-landing function being able to have superior shock absorption function while walking and to enhance ventilation property through smoothly flowing a fresh air outside a shoe into an inside of the shoe.BACKGROUND ART[0003]Generally, person wears shoes to her or his feet and to facilitate her of his movement.

AI Technical Summary

Benefits of technology

The invention provides a shoe that can generate air during walking and absorb shocks, resulting in comfortable and pleasant walking. It achieves this by using a pressure pad that increases the inner pressure, allowing for more air generation. The shoe also has a double-landing feature that prevents slips and ensures safe walking. The pressure pad and groove formed at the elbow and heel allow for increased air generation and shock absorption. The shoe can be used for various shoes and also helps prevent bacterial infections.

Problems solved by technology

Accordingly, an inside of the shoes and the feet smell bad, and the feet get chronic diseases such as athlete's foot.
