Description

The present invention relates to an insole used for a shoe, and more particularly, to an insole for a shoe used for a shoe having a high heel like a high heel and a load concentrated on a forefoot part.

Recently, there have been provided shoes that have various functions beyond the dimension of protecting the foot and are designed to be suitable for special applications. Typically, there are shoes that increase the effect of exercise, shoes that are suitable for diabetic patients, and shoes that are used for special exercise.

For humans who walk upright, the foot is a body part that is so important that the foot is called the second heart, except for the role of supporting the body load. If the shoes are not comfortable to wear, it will be easier to feel tired, resulting in various diseases.

In particular, women may have problems due to foot deformation because women often wear high-heeled shoes, unlike men, unlike men. Many young women prefer high heels because wearing high-heeled shoes such as high heels can enhance the beauty of the woman. However, when wearing high heels, the toes deform into an arch shape because the center of weight concentrates on the front of the high heels and the toes are bent. In addition, if such a phenomenon occurs, the toe muscles deform and contract, and the toe shape does not become normal. And if you wear high heels for a long time, you will feel tired early or symptoms that may decrease your mental concentration. cause.

Since wearing high heels is different from a general human walking posture, it involves many problems as described above. In order to maintain foot health, it is preferable to wear shoes with low heels, but for women, high heels are a necessary evil. Under such circumstances, there is a need for a method that is comfortable to wear when wearing high heels and that can minimize problems such as deformation of the foot.

In other words, there is a high need for high heels that can alleviate the concentration of load on the forefoot and at the same time actively induce good comfort. As a method for artificially enhancing the comfort when wearing high heels, there is a method of actively stimulating the spring hole in the sole.

The spring hole corresponds to a concave part forming the arch part of the sole, and stimulating the spring hole stabilizes the heart activity and is known to be very effective for high blood pressure, low back pain, asthma, etc. .

As a conventional technique related to the present invention, there is "a shoe and an insole for preventing slipping of a foot and concentration of load" of Patent Document 1, and FIG. 1 shows an embodiment according to the conventional technique. It is a perspective view shown. As shown in FIG. 1, in the conventional technique, the insole 11 has a plurality of anti-slip members 12 formed at equal intervals on the upper surface of a stretchable sheet 13. It is formed long in the width direction. In the prior art, a straight anti-slip member 12 is formed in the shape of a washing plate at a portion where the sole contacts with the upper surface of the insole without any special condition, and is configured to prevent slipping and tilting. The

In particular, in shoes such as high heels where the load concentrates on the front even when walking on flat ground, the selection and number of the exact position of the non-slip members described in the prior art is important. There is a need for a method that can stimulate the wells to induce good comfort.

And in the case of an insole used for shoes such as general high heels, it is formed thinly and entirely with what is called a traction 1 made of paper material, and an iron core 2 is formed from the metatarsal at the lower portion of the traction 1. To maintain the outer shape of the shoe. FIG. 2 is a perspective view showing a configuration of an insole used for a schematic conventional high heel. A bottom plate 3 is further provided below the iron core 2, and the iron core 2 is provided between the protection 1 and the bottom plate 3. The bottom plate 3 is also made of paper. Since the insole constructed as such has no cushioning ability, the shock is transmitted to the sole as it is, and it becomes easy to feel foot pain and tiredness. Hereinafter, the conventional insole for high heels composed of the traction 1, the iron core 2, and the bottom plate 3 is referred to as “frame f”.

Because of their morphological specificity, shoes like high heels inevitably cause the wearer to experience problems such as severe pain and toe deformation, and if such problems become more severe, surgery is required. It also occurs when you have to receive it. Providing better comfort can contribute to maintaining the health of the body as a whole, so research on it must be sustained, and as long as there is sufficient demand, it is an area with unlimited potential Will.
