The present invention relates to a shoe to correct the posture while absorbing the impact when walking, specifically, the movement of weight when rolling the foot while buffering the shock acting on the heel when walking the foot during walking And a shoe having a functional sole structure which is naturally made from the outer part of the sole to the inner part of the foot and the big toe part.

Shoes are generally used to protect the feet, and in particular, many studies have been conducted on the soles to prevent shock absorption and deformation of the feet and to allow correct walking.

Thus, the outsole can be divided into the insole upper sole midsole insole from the upper side, each of which functions differently. First, the insole is made of a soft and flexible material such as a sponge or soft rubber to be comfortable to wear while being in direct contact with the sole of the shoe to cushion the impact. The upper window is to maintain the shape by sewing or adhesively fixing the lower edge of the outer covering covering the foot is formed of a hard leather or pulp material so as not to tear or tear. The midsole is formed of a rubber or synthetic resin material having a certain thickness and elasticity to prevent the foot from being folded or bent while buffering the shock transmitted to each part of the body, such as the spine, joint, foot, etc. by weight when walking. The sole is made of hard rubber or synthetic resin as preventing the midsole from being worn while preventing slipping while walking.

Therefore, the shoe sole structure of the conventional shoe is slightly higher than the toe portion, but the cushioning acting on the front, rear, left and right while maintaining the overall gentle height is formed uniformly.

However, the sole structure of this configuration has a very large impact transmitted to the first heel when walking the foot, and even when the foot is rolled, it is usually used locally for only the outer edge of the foot, so that it becomes accustomed to the wrong gait. There is a problem.

In other words, while walking while stepping and rolling the foot continuously, the conventional sole structure does not have a continuous stepping and rolling motion, so the impact acting on the heel in the stepping step is inevitably increased.

In addition, in the process of rolling the foot, it is a proper posture to naturally connect from the outer part of the heel and the floor to the inside of the foot and the big toe. In the conventional sole structure, since the front, rear, left, and right sides have uniform elastic force, Only the outer blades can be buffered locally. Moreover, using only the outer blade portion of the sole like this can cause serious problems that cause the foot to deform while wearing only that portion.

The main purpose of the present invention to solve the problems and shortcomings of the present invention is to shift the weight when rolling the foot while buffering the shock acting on the heel when walking the foot inside the foot from the outside of the heel and the sole of the foot And to provide a shoe with a functional sole structure that is made naturally to the big toe part.

Another object of the present invention is to provide a shoe having a functional sole structure that further cushions the impact on the heel and at the same time provides ventilation to the front of the sole.

Another object of the present invention is to provide a shoe having a functional sole structure to facilitate the blood circulation of the sole.

The present invention for achieving the above object is a shoe including the configuration of the outer shell and the sole to be worn on the foot, the sole is insole formed in direct contact with the sole; An upper window formed to fix the lower edge of the shell; It has a constant elasticity and its bottom is formed to have an arcuate curve extending from one point of the rear end to one point of the front end, and streamlined indents upward on another point from the middle point of the arch curve to the one point of the rear end. Midsole with formed spaces; In the state closely fitted in the recessed space of the midsole, the bottom is formed to match the arch curve formed by the bottom of the midsole, the inside of which formed at least one hole in a position corresponding to the outside of the sole bottom Auxiliary window spring is coupled to the inside of each hole in the state; And a lower sole formed to cover an arch bottom formed by the midsole and the auxiliary window; Is done.

At this time, the auxiliary window is made of a material having a different elasticity between the inside and the outside, the outside is made of harder than the inside.

In addition, an air pump is formed at the heel portion with respect to the inside of the insole, and an air tube having a plurality of air ejecting ports is formed at the sole portion to extend from the air pump to blow air upward.

At this time, the bottom of the insole is formed by attaching at least one magnet.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Footwear having a functional sole structure of the present invention is composed of a shell 100 and a multi-layered sole 200 as shown in Figures 1 to 9, thereby cushioning the impact acting on the heel when walking the foot during walking As you roll the foot, the weight shifts naturally from the heel and the outside of the sole to the inside of the sole and the big toe.

Thus, the outer shell 100 is stitched to form a leather or cloth so as to cover the foot, such as the bottom of the outer shell 100, the upper edge 220 described above by folding the lower edge in a predetermined width in the drilled state Through sewing or adhesive fixation. On the other hand, the outer shell 100 may be cut to the front to form a knot with a string.

The sole 200 is composed of a large insole 210, upper sole 220, midsole 230, auxiliary window 240 and the lower sole 250.

Thus, the insole 210 is made of a soft and flexible material such as sponge or soft rubber to comfort the shock while being in direct contact with the sole and to cushion the impact, while attaching a thin fabric to the upper side. At this time, the insole 210 is located on the upper window 220 in the inner side of the outer shell 100, it is possible to adhesively fixed with the upper window 220.

In particular, the insole 210 of the present invention forms an air pump 212 and the air tube 214 therein to cushion the shock and at the same time form the air to be ejected to the sole. That is, the heel portion of the insole 210 forms an air pump 212 formed of a rubber material, the sole portion is a plurality of air outlets 216 to extend from the air pump 212 to eject the air upwards To form an air tube (214).

In addition, at least one magnet 218 is attached to the bottom of the insole 210, particularly preferably at a position corresponding to the spring portion of the sole.

The upper window 220 is formed to fix the lower edge of the shell (100). That is, the upper window 220 is to maintain the shape by sewing or adhesively fixing the lower edge of the outer shell 100 covering the foot and is formed of hard leather or pulp material so as not to be torn or torn.

The midsole 230 has a constant elasticity and its bottom is formed to have an arcuate curve extending from one point of the rear end to one point of the front end, and on another point extending from the middle point of the arch curve to the one point of the rear end. A streamlined recessed space is formed on the upper side. That is, the midsole 230 is formed as a whole, while forming a thick rounded arch from the heel to the toe, so that the stepping and cloud action of the foot when walking naturally, and the upper side of the outer shell 100 and the upper surface described above An edge is formed so that the 220 is adhesively fixed, and a recessed space is formed at the lower rear thereof to allow the auxiliary window 240 described above to be coupled thereto. At this time, the midsole 230 is formed of a relatively hard rubber or synthetic resin having a certain elasticity to prevent the foot from being folded or folded while buffering the impact when walking.

The auxiliary window 240 is formed so as to match the arcuate curve formed by the bottom of the midsole 230 in a state that is tightly fitted in the recessed space of the midsole (230). At this time, the auxiliary window 240 is preferably formed of a softer sponge or rubber material than the midsole 230 so as to fully cushion the impact while the weight is naturally deformed along the movement of the foot step and cloud when walking. .

In addition, at least one hole 242 is formed at a position corresponding to the outside of the foot bottom in the auxiliary window 240, and a spring 244 is formed in the hole 242, respectively. At this time, the spring 244 is such that the center of gravity is naturally moved to the inside of the foot when the foot is rolled with an elastic force greater than the elasticity of the auxiliary window 240 itself. That is, when the foot is rolled, the spring 244 having elasticity pushes the outer side of the rolled foot so that the balance is inclined toward the inside of the relatively low elasticity, thereby moving the center of gravity. Therefore, in the process of rolling the foot, the movement of weight naturally occurs from the heel and the outer part of the sole to the inner side of the sole and the big toe.

At this time, the Maasai people are barefoot on a large land in Africa, and it is well known that the legs, waist and spine are straight and healthy through the acquisition of many walking and correct walking.

Meanwhile, in forming the auxiliary window 240, the inner auxiliary window 240 ′ and the outer 240 may be formed of materials having different elasticities, so that the aforementioned weight movement may be more smoothly performed. At this time, it is preferable that the outer auxiliary window 240 is formed to be harder than the inner auxiliary window 240 '.

The lower sole 250 is formed to cover the bottom of the arch formed by the midsole 230 and the auxiliary window 240. At this time, the bottom of the sole 250 is formed of a hard rubber or synthetic resin while forming a lot of irregularities to prevent the midsole 230 to wear while preventing slipping when walking.

Therefore, according to the shoe of the present invention made of such a configuration it is possible to correct the posture while buffering the impact when walking.

Although the present invention as described above has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art may various modifications and other equivalent embodiments therefrom. Will understand. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
