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.

Description

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

[0027]The shoe sole of the present invention can improve shock absorption and dispersion and contribute weight lightening of a shoe.

[0028]Specially, by using a cushion column in which multi-level cushion layers are piled vertically, the shoe sole of the present invention can effectively absorb and disperse the shock generated when walking or running.

[0029]Each of the cushion layers may be deformed elastically under a different load condition, so as to absorb the shock with various shock absorption abilities according to the user's physical conditions, such as weight. For example, in the present invention, different cushion layers may perform shock absorption respectively according to the user's weight. To one user having about 270 mm of shoe size and about 60 kg of weight, only one cushion layer located on top may be elastically deformed, while to another user having the same shoe size and about 100 kg of weight, two or more cushion layers may be elastically deformed to support relatively heavy load. Accordingly, the customized shoe sole of the present invention may provide differently optimized shock absorption abilities according to the users' weights with the same shoe size.

[0030]By actively controlling the shock absorption ability according to the exercise conditions, the shoe sole of the present invention can absorb shock effectively in various conditions. For example, it is known that the shock during running is larger than the shock during walking by about 2-3 times. According to the present invention, one or two of the cushion layers in one cushion column may perform shock absorption when walking, and two or more of the cushion layers may perform shock absorption to support the increased load in order when running. Like this, the customized shoe sole of the present invention may provide differently optimized shock absorption abilities according to exercise conditions, such as walking or running.

[0031]According to the present invention, a plurality of the cushion columns may be distributed in the shoe sole by being horizontally separated to each other, so as to protect the user's foot from lateral shock. In case that the cushion column is formed integratedly in one body, the lateral shock may not be absorbed and be transmitted to the whole of the shoe. But in case that a plurality of cushion columns are distributed and separated to each other, the lateral shock may be absorbed and dispersed effectively due to spaces in the shoe sole.

[0032]Therefore, the customized shoe sole of the present invention can provide an improved wearing feeling, help the user's easy walking and minimize the tiredness of 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.
