Footwear having shock-absorbing means

Abstract

Disclosed herein is footwear. The footwear includes a midsole, a shock absorbing means, and an outsole. The midsole has on an upper surface thereof an air passage. At least one insertion recess is provided in a lower surface of the midsole and communicates with the air passage. The shock absorbing means is made of an elastic material and movable up and down by flow of air present in the shock absorbing means. The upper end of the shock absorbing means is opened and secured to the insertion recess of the midsole, and the lower end of the shock absorbing means is closed and protrudes downwards. The outsole functions to secure the shock absorbing means to the midsole. The present invention provides footwear having a shock absorbing means having a simple structure and a superior shock absorbing function, thus having high durability.

Description

TECHNICAL FIELD[0001]The present invention relates, in general, to footwear and, more particularly, to footwear having a shock absorbing means using air so as to efficiently protect a wearer's feet from external shocks while he or she walks.BACKGROUND ART[0002]Footwear is developed to efficiently protect the feet of a person, who walks erect, from the external environment, such as the ground, and to increase friction relative to the ground, thus improving walking ability. Since then, footwear has been continuously improved to have various functions. Recently, among various functions of the footwear, interest in shock absorbing functions for efficiently absorbing external shocks has increased.[0003]Generally, the shock absorbing function of footwear is achieved by variously changing the material of a sole to increase the shock absorbing capability thereof, or by inserting a shock absorbing material into the sole. The former method is advantageous in that no additional insert material...

AI Technical Summary

Benefits of technology

[0020]As described above, the present invention provides footwear, which is constructed so that a shock absorbing means, having a simple structure and a superior shock absorbing function, performs only a shock absorbing function, thus having high durability, therefore allowing the footwear to be used for a lengthy period of time.

[0021]Further, the present invention provides footwear, which is constructed so that an unevenness serving as a shape support means is provided on a shock absorbing means, thus efficiently absorbing external shocks without any deformation, even if the footwear is used for a lengthy period of time.

[0022]Further, the present invention provides footwear, which additionally has a shock absorbing space in the bottom of a shock absorbing means, in addition to having the shock absorbing means, thus more efficiently distributing shocks.

[0023]Furthermore, the present invention provides footwear, which further includes a reinforcing plate between a shock absorbing means and an outsole, thus more efficiently protecting a wearer's feet from a rough road, in addition to securing a shock absorbing function.

Problems solved by technology

However, it is disadvantageous in that the sole itself is made of a single material, so that a sufficient shock absorbing function cannot be provided to footwear as desired.

However, it is problematic in that the bottom of the cushioning member is in direct contact with a road surface, so that the durability of the cushioning member may be deteriorated when a person wears the footwear for a lengthy period of time.

Further, this invention is problematic in that there is no means for helping the cushioning member continuously maintain a predetermined shape when the cushioning member performs a shock absorbing function in a vertical direction, so that the cushioning member may be deformed after long use.
