Customized shoe sole having multi-level cushion column

Abstract

Disclosed is a customized shoe sole having a multi-level cushion column, which can improve impact absorption and dispersion while walking. The customized shoe sole comprises at least one multi-level cushion column including a plurality of cushion layers piled vertically, wherein at least one of the cushion layers has an elastic hardness different from those of the other layers, so as to start to be elastically deformed under a specific load condition.

TECHNICAL FIELD[0001]The present invention relates to a shoe sole, more particularly, relates to a customized shoe sole having multi-level cushion column, which can improve shock absorption and dispersion and contribute weight lightening of a shoe.BACKGROUND OF THE ART[0002]In past, a shoe was for protecting a foot, however, as one's quality of life is getting improved recently, the shoe is needed to have other function or property.[0003]Specially, contrary to the past trend that a pair of athletic shoes were used for multipurpose, various type of shoes are being developed in these days, such as for walking, running, mountain climbing, soccer, tennis, baseball, golf and the like.[0004]A shoe comprises an upper part for protecting an instep and joints of the foot and a sole part for protecting the sole of the foot. The sole part of the shoe transfers impact generated when walking and running. Since a walker wearing shoes having hard sole parts may feel fatigue easily, the sole part s...

AI Technical Summary

Benefits of technology

The present invention is a shoe sole that improves shock absorption and dispersion, and contributes to weight lightening of a shoe. By using a cushion column with multiple levels of cushion layers, the shoe sole can effectively absorb and disperse the shock generated while walking or running. The different cushion layers can elastically deform and absorb shock with different abilities according to the user's weight. Additionally, the cushion column can protect the user's foot from lateral shock, which results in improved wearing feeling, easy walking, and minimized tiredness of the foot.

Problems solved by technology

There have been studies about shoe soles which can reduce impact generated when walking and running and contribute to weight lightening, however they have left much to be desired.

The conventional shoes have been manufactured depending only on user's foot size, not considering his weight, so they cannot absorb impact effectively, when supporting heavy users.

For example, since the conventional shoe of 270 mm has only one shock absorbing ability regardless of users' real weights, for example 60 kg or 100 kg, the conventional shoe cannot provide a proper shock absorbing ability which can be varied according to their weights.

Also, the conventional shoes have been manufactured to have a general shock absorbing ability, however they cannot absorb shock in various conditions.
