Description

Improved insole construction

technical field

The utility model relates to an improved insole structure, in particular to an insole structure which can be inserted or extracted at will and can correct foot posture.

Background technique

The foot structure of the human body has 26 bones. When the human body is standing, the root of the first metatarsal, the heel of the fifth metatarsal, and the calcaneus are three points of support. The first metatarsal and the fifth metatarsal are not in a horizontal state. , but the first metatarsal is lower than the fifth metatarsal, and then the arch is formed by three points distributed in height to support the body; the human foot must maintain a certain arch, so that it is elastic and not easy to fatigue when walking. And shoes are a basic wear to protect the feet when walking or running, because the weight supported by the human feet is about one to two times the body weight, therefore, there needs to be a good insole in the shoes to protect the feet, To prevent damage to human bones, joints and muscles.

Currently on the market, all shoes contain insoles (liners). The insoles can be roughly divided into two types, one can be taken out by itself, and the other is fixed on the sole and cannot be taken out. The main function is to provide appropriate softness. Increase the sense of comfort; yet the existing movable insoles 2 circulating on the market that can be replaced or installed in the shoes are mostly flat pads (as shown in Figure 4), and the material selection is mostly foaming material molding-thickness approx. It is a bottom layer of 3mm to 7mm, and a surface layer is combined on the upper surface of the bottom layer. The surface layer can be mesh breathable fiber, general cloth, artificial leather or genuine leather. The above-mentioned insole 2 is mainly used as a soft lining in the shoe and as a supplement for the excessive gap between the shoe body and the foot. Therefore, this type of insole 2 can only provide cushioning and pressure-dispersing effects at the three support points of the aforementioned feet, and does not provide any support for the transverse arch of the human foot. When the human body is standing or walking, The pressure and weight exerted by the human body on the bow of the forefoot cannot be borne and cushioned by a straight insole, but still needs to be borne by the elasticity of the bow of the forefoot. In other words, the traditional insole 2 cannot support the bow of the forefoot, nor can it relieve standing Or the pressure of the forefoot when walking. This type of insole 2 is cheap in price and low in manufacturing cost, so it does not emphasize or provide functions that meet foot mechanics or other functions that are beneficial to sports and walking.

In addition, there is an insole structure that thickens the shock absorber at the high pressure part corresponding to the pressure plate on the sole of the foot. This can indeed reduce the stress on the high pressure area, but the pressure will be transferred to the arch of the foot and other non-tread parts to bear , which cannot be reflected by the foot pressure plate in real time, and will cause pain in the foot and fascia in the long run.

Therefore, in view of this, the designer has been adhering to years of rich experience in design, development and actual production in this related industry, researched and improved the existing structure and defects, and provided an improved insole structure in order to achieve better practical value.
