When the shoe is worn while standing with the shoe sole of the present invention according to such a configuration, the shoe is in a state of being collected inward as shown in FIG.

When the shoes are collected inward, the load on the shoes is also collected inward, reducing the fatigue of standing.

That is, in standing state, the load of the body is divided into both feet, but in the shoe, the load is gathered again inward, so that the load applied to both feet prevents the dispersion of the force and enables easier and safer wearing of shoes.

In addition, in the standing state is inclined inwards over the main body 10 or the front axle 110 in front of the heel under the most load, so it serves to collect the feet and feet.

Therefore, when the feet are gathered inward, the contact with the ground at an angle close to the angle between the foot and the foot is performed, so that the pressure applied to the foot can be reduced more at the same time to balance the power.

FIG. 15 is a side view illustrating a process of wearing and walking shoes to which a shoe heel is applied according to the present invention, and FIGS. 16 to 19 are views illustrating a process of wearing and walking shoes from the rear.

Unlike standing, when walking, the rear end of the heel 20 or the rear axle 120 first touches the ground.

When the weight is loaded while touching the ground, the foot is turned inward while the contact surface with the ground moves naturally from the outer end formed by the heel of the heel 20 or the rear axle 120 to the inner end of the lower heel. do.

As the body moves forward, the weight applied to the shoes gradually increases, so when the heel 20 or the heel 120 is in close contact with the ground, the shoes are in a state of inducing a step at a certain angle.

The moment the weight is placed on the heel 20 or heel 120 of the shoe, the ankle is in a straight out state so that the weight burden at the ankle is further reduced.

On the other hand, when the flat part and the inclined part of the shoe contact the ground at the same time, the part where the flat part and the inclined part contact with each other is spaced by a certain height from the ground as shown in FIG. The surface spaced a certain distance from the contact with the ground as shown in FIG.

Therefore, the weight can be absorbed and mitigated the impact of the moment touching the ground through the space spaced from the ground to further mitigate the impact on the ankle by the cushion action through this space.

When the part in contact with the ground moves forward from the heel 20 or the rear axle 120 of the shoe, the body 10 or the front axle from the flat portions 21, 121 of the heel 20 or the rear axle 120. While moving naturally to the flat portions 11 and 111 of 110, the load by weight already is transmitted to both feet evenly.

Since the body weight is already moved forward of the shoe while passing through the flat portions 11 and 111 of the main body 10 or the front shaft 110, the strength of the weight applied to the shoe is gradually weakened.

Therefore, just before the shoes fall off the ground, the bottom surface of the main body 10 or the front axle 110 having the lowest heel height, in particular, the bottom end portion of the inner end is in contact with the ground to direct the shoes further inward.

This ensures that the shoes are always gathered inwards while walking, providing the flexibility of the ankle at the moment of walking while minimizing the weight burden.

By minimizing the burden of the load, even if you walk for a longer time, the burden is eliminated, the slip can be prevented as much as possible.

In particular, the long gait prevents the deformation of the spine and at the same time allows correction of the vertebrae, and it is possible to provide the most desirable 3-time gait for upright walking while reducing fatigue even during long walking.

As described above, the present invention allows the sole of the shoe sole to be formed with a higher height of the heel gradually from the inner side to the outer side, and the front sole is formed to have a lower height of the heel from the outer side to the inner side so that the user can stand or walk while wearing the shoe. Always keep your feet, ankles and shoes in line to provide an ideal three-time walk.

In addition, the present invention is to disperse the natural center of gravity of the human body while moving from the outside of the shoe to absorb and relieve the impact force applied by the weight to reduce the fatigue of the foot, to prevent and correct malformed steps such as limb walking To prevent slipping while walking.

In particular, the present invention has a very useful effect of providing a shoe sole that is ergonomically designed to be suitable for the structure and walking of the foot so that the correct gait can be naturally and continuously maintained, thereby preventing deformation of the spine and correcting it naturally.
