FIG. 6 is a cross-sectional view of a sole according to an embodiment of the present invention, FIG. 7 is a cross-sectional view taken along the line CC of the sole of FIG. 4 of the present invention, FIG. 8 is a side view of the sole according to an embodiment of the present invention And FIG. 10 is a view showing the state of use of the sole according to an embodiment of the present invention.

6 to 8 and 10, the state of use of the sole according to the embodiment of the present invention will be described below.

Here, the shoe can be worn by the wearer through an upper part joined to the upper part of the shoe sole.

At this time, the medial side of the sole corresponds to the arch shape of the insole 90 to support the sole of the wearer.

And the wearer's heel is supported on the protruding member 91 of the insole 90 and the forefoot is supported by the first sponge layer 73, the second sponge layer 75 and the ventilation member 77 of the middle 70, do.

In this state, the wearer makes a walk, and the sole 10 is sequentially contacted and separated from the ground surface from the heel 13 to the heel 11.

At this time, the heel 13 is formed in a round shape and supported on the ground, thereby reducing impact transmitted from the ground.

At the same time, the impact transmitted from the ground through the dechucking 13 is buffered through the second shock absorbing means 35.

That is, the second shock absorbing means 35 is deformed in the second groove 13a to buffer the impact transmitted from the debris 13.

Here, the second impact buffering member 55 disperses a load generated in the heel, and presses the second shock absorbing means 35 through the second compression protrusion 57. [

Then, the second impact buffering means (35) is compressively deformed by the pressing force of the second compression protrusion (57) to buffer the shock.

The front shock absorber 30 and the front shock absorber 30 contact the front sheath 11 to cushion the impact transmitted from the front sheath 11.

Here, the first impact buffering member 50 disperses the impact and the load in the first groove 11a through the shock dispersion protrusion 53, and the first impact buffering means 30).

Then, the first impact buffering means (30) is compressively deformed by the pressing force of the first compression protrusion (51) to buffer the impact.

Herein, the midsole 70 absorbs the impact of the ground transmitted from the pressing unit 11 through the sponge layer 73, the second sponge layer 75, and the ventilation member 77.

The middle window 70 is made to buffer the impact of the ground transmitted from the heel 13 through the cushion member 79, the insole 90 and the protruding member 91.

On the other hand, the heel 11 and the heel 13 of the sole 10 are sequentially separated from the ground, and the first and second shock absorbers 30 and 35 are separated from the first and second grooves 11a and 13a ).

On the other hand, the outsole 10 is formed so that its outer side is higher than the inner side, and the feet of the wearer are gathered inward by the difference between the inner height D1 and the outer height D2.

That is, when the wearer wears the shoe to which the sole 10 is applied regularly, the wearer's feet are gathered to the inside and the joints that are widened are gathered inward, so that the erroneous posture of the joint such as the stool can be corrected correctly .

Therefore, in the shoe sole according to the embodiment of the present invention, the impact of the ground occurring when the wearer walks after wearing the shoes is applied to the first and second shock absorbing means 30 and 35, the first and second shock absorbing members 50 and 55, The midsole 70 and the insole 90 to effectively protect the wearer's joints by buffering and dispersing the shock transmitted to the forefoot and the heel.

The shoe sole according to an embodiment of the present invention as described so far has the first and second grooves 11a and 13a formed in the heel 11 and the heel 13 of the sole 10, The first and second shock absorbing members 50 and 55 that cover the first and second shock absorbing members 30 and 35 and the first and second grooves 11a and 13a, The shock generated from the ground can be buffered and dispersed through the middle 70 and the insole 90 stacked on the upper portion of the midsole 70 to protect the wearer's joints.
