The present invention relates to a shoe pad, and more particularly, to improve the body's orthodontic effect on the case of deviating from the normal adduction movement while absorbing the shock received from the ground while walking, and to distribute the load concentrated on the sole. It's about a shoe pad.

In general, the shoe is roughly an upper (upper) surrounding the foot, an outsole for protecting the sole surface when walking, and a midsole for intervening between the upper and the sole of the sole to increase the fit by shock absorption ( Interposed on the midsole and the upper inner bottom surface is largely composed of an insole (insole) to give a more improved fit.

In general, when walking or running with such shoes, the impact from the ground is mainly absorbed by the sole or midsole, and thus, the sole or midsole made of various materials and structures has been developed to give a better shock absorption function. Has been.

On the other hand, as is known, in normal people, when the foot touches the ground, the ground touches the ground from the outside of the heel of the foot and then the inside of the heel touches as the ankle is rolled inward, then the center of gravity is moved toward the front of the foot. In so doing, so-called pronation is performed to swing outward again, ie to minimize the impact on the foot.

However, in some people, when the center of gravity moves from the outside of the heel to the inside, the ankle may turn excessively inward. Arch) ') does not function properly and can not absorb shock, which is the main cause of injury.

In addition, in the human body, which is a biomechanical body, the skeleton of the whole body is arranged symmetrically about the spine, and has a ring-shaped connection structure in which every node is in a close relationship. This can affect the activity of other joints.

 In other words, if the arrangement of each part of the foot is not correct, the heel is twisted in the end, and this causes the tibia (leg bone) to be balanced, so that when walking, the impact is not evenly distributed to the sole through the knee and ankle.

If this phenomenon persists for a long time, it causes an imbalance between the systemic skeleton and the joint, and also affects the knee, hip, pelvis, and spine, causing pain in the joint. Among them, the twisting of the pelvis (elbow) creates tension in the muscles and connective tissue, causing chronic low back pain, impairing the spine, reducing the body's ability to absorb shock, and reducing the buffering capacity of the legs and pelvis. Received vibrations propagate to the top (head), leading to worsening head pain (migraine, temporal pain) and other pain.

U.S. of America According to a survey by the Public Health Service, 87% of urban dwellers have problems with their feet, and these problems began as a child. Moreover, the problems caused by the arrangement of the bones are gradually developing into chronic diseases such as scoliosis, lower back flexion, sagging of one shoulder, back and neck stiffness and stiffness and pain.

On the contrary, there is a case in which there is little or lack of inward movement, and even in this case, the shock absorption is not made well, and thus, the user is unable to walk for a long time.

However, in the case of the conventional shoe, the case where the corrective means are specially given to the case of deviation from the normal adduction movement as described above is mainly composed of a multi-density which varies the density for each part of the sole or midsole. And there has been a problem that does not vary according to the degree of curvature of the arch of the sole surface.

In particular, the sole or midsole made of multi-density is not in direct contact with the sole of the foot that the user directly feels, so the correction effect is inadequate. In the case of the sole, the relatively low density part is easily damaged and the durability is also reduced.

In addition, in the case that the shoe is provided in the sole or the midsole of the correction means is not only very expensive, there is also a disadvantage in terms of economic disadvantages, such as the need to purchase the entire shoe again if the sole or midsole is damaged.

Accordingly, the present invention has been proposed to solve the above-mentioned conventional problems, to provide a shoe pad that can distribute the load concentrated on the heel while absorbing while absorbing evenly the impact received from the ground during walking. There is a first purpose.

The present invention is to provide a shoe pad that can correct the abnormal arrangement of the foot bones to allow correct walking and gradually restore the balance of the body skeletal structure and relieve the pain of each part caused by the body imbalance. There is this.

Here, the synthetic resin is preferably TPU (Thermo-elastic Polyurethane) excellent in strength and excellent elasticity, the antibacterial agent is silver or other inorganic antibacterial agent, the deodorant is a porous powder, the fragrance is a microencapsulated fragrance, The far infrared emitter may use tourmaline powder.

In addition, it is light and resilient and its structure is not easily broken due to its content ratio of 99.9% antibacterial, 99.9% deodorization rate and 92,7% far-infrared emissivity. Can be.

More specifically, the antimicrobial agent, deodorant, fragrance, and far-infrared radiator are added to the main raw material in a predetermined weight ratio while dissolving the TPU or the resin chip in the melting furnace at 260 ° C., and then the mixed melt is mixed into the shape of the pad body or the calibrating part. Each of the molds is supplied to each mold to be injection molded.

In this case, the pad body 110 and the correction unit 120 may be formed by injecting a pigment set in advance into the mixed melt before injection molding so as to have different colors to facilitate visual identification.

Shoe pad 100 manufactured by inserting the correcting unit 120 and the shock absorbing unit 130 into the front and rear recesses 112 and 114 provided on the upper surface of the pad body 110 manufactured as described above. The arch of the sole and the corrector 120 correspond to each other, the heel of the sole and the shock absorbing unit 130 is provided in the shoe to correspond to each other.

When the user having various weights and arch curvatures determines that the arch of the sole and the correcting part 120 are too weak to be interviewed after the shoe is worn with the shoe pad 100, the front recess 112 ) Is replaced by another calibration unit having a relatively large degree of curvature of the upper surface of the calibration unit 120, and remounted. If it is determined that the walking is uncomfortable due to excessive, the upper surface curvature degree of the correction unit 120 is replaced with another correction unit formed relatively small and remounted.

Accordingly, if the arch of the sole and the corrective portion 120 is evenly elastically interviewed with each other, when the center of gravity is moved to the outside of the sole during walking, the ankle is prevented from turning excessively inward, and applied to the foot Since the adduction movement can be stably performed to minimize the impact, the skeleton, ligaments and muscles of the foot can be corrected to be normally disposed or grown.

While the invention has been shown and described with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit or scope of the invention as set forth in the claims below. I would like to clarify that knowledge is easy to know.
