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. Various types of shoes are manufactured to various types in order to satisfy various functional aspects needed according to improvement of the standard of living and widening activity area of person. For example, there are various types of shoes such as running shoes, formal dress shoes, work shoes, boots, hiking boots, and so on.[0004]As su...

AI Technical Summary

Benefits of technology

[0007]According to an embodiment of the invention, an air is freely generated during walking and is supplied to an inside of a shoe. A pressure pad protrudes toward the ground, and thus, an area of an inner space between the pressure pad and a groove formed at a mid-sole increases. Also, the force applied to the mid-sole from a body during walking and the force applied to the pressure pad from the ground are simultaneously generated, and thus, an inner pressure increases. As a result, an air-generation amount improves and a shock-absorption force increase, thereby enabling pleasant and comfortable walking.

[0008]Also, a slip during walking can be prevented by a double-landing through a mutual operation of the pressure pad and the bottom surface of the sole. Accordingly, safe walking can be possible.

[0009]Further, in the embodiment of the invention, the pressure pad and the groove are formed at an entire area of elbow and a heel, and communicated to each other through a flow path pipe. Therefore, the air-generation amount and the shock-absorption force can increase more.

[0010]By the above functions, pain of joints, such as a heel, an ankle, a pelvis, and a spine, can be relived. The pressure of the foot can be distributed. Also, bacterial affections such as athlete's foot and eczema can be prevented by generating and ventilating air. Thus, the shoe sole can be applied to various shoes as well as shoes for foot-disease patient (for example, a patient having foot disease due to diabetes).

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.
