Foot stabilization device

The present invention is a foot stabilization device, and more particularly to a foot stabilization device that reduces the force of foot contact by reducing the force structure.

The human body's foot is made up of 26 bones and 33 joints. It is covered by more than 100 muscles, tendons, ligaments, blood vessels, nerves, skin and soft tissues around these bones and joints. Whether it is standing or walking, the operation of the entire foot is very large.

Because the foot is mainly used to support the structure of the human bones and the overall weight of the muscles, and the muscles and bones of the human body are intertwined with each other. When there is a problem with the structure of the foot, it will affect the knees and the pelvis at the same time. It can even cause the spine to become skewed, and it is more likely to affect the function of the organ from the bone structure. In order to solve and avoid the above problems, foot medicine has begun to be gradually taken seriously.

In international foot medicine, insoles are often used as foot aids to correct and deal with problems in the foot. However, the existing auxiliary insole is mostly based on the three-point mechanics of the human arch, which makes the transverse arch of the foot arch, the medial arch and the lateral arch reach the balance of three points. Although the existing insoles have a wide variety of Design, but even at the three support points of the three-point mechanics - the first metatarsal, the fifth metatarsal and the heel, the design of the convex or concave, or the design of the heel cup is used to coat and stabilize Foot. However, after a long walk, the foot will still be displaced due to muscle fatigue, so that the contact position between the foot and the insole will be displaced, so that the foot will slide on the insole, which will cause the foot to be unstable.
