Description

[Detailed Description of the Invention] The present invention relates to health shoes that prevent foot fatigue and maintain foot health.

The sole of the human foot has three arches, namely, two longitudinal arches, medial and lateral, and a transverse arch in the forefoot.The medial longitudinal arch is especially large and can be easily seen from the outside as the arch of the foot.

These arches play the role of springs that soften the cushion of the foot when walking and help shift the weight load on the sole of the foot from the outside to the inside. When the feet are loaded for a long period of time, such as by standing for long periods of time, the muscles in the feet not only become fatigued, but the talar head of the foot is pushed down, the navicular bone is lowered, and the plantar fascia becomes weaker. In this order, the heel becomes overstrained, the deltoid ligament becomes overstrained, and the heel becomes everted.
The skeletal structure of the foot is deformed and the arch deteriorates,
Scientists have reported that foot fatigue, foot pain, and foot deformity may occur. However, many conventional shoes do not have a structure that prevents this arch depression.

The purpose of this invention is to make the part of the upper that extends from the inner sole to the side of the shoe, from the quarter part to the area around the heel, hard, and the inside of the shoe has enough height and elasticity to support the inner arch of the foot. The shoes have an arch cushion and a built-in shank in the arch of the leather sole to increase the resilience of the sole against bending, thereby preventing arch deterioration due to deterioration of the navicular bone and maintaining foot health. Our goal is to provide you with healthy shoes.

Below, an embodiment of the present invention will be described based on the drawings. Shoes 1, which can be applied to work shoes, athletic shoes, and other various health shoes, are light and strong, and have a built-in shank in the arch of the sole. The sole is made to be easily bent in front of the built-in shank, ie, at the base of the toe.

The outside of the shoe 1 is covered with an upper leather 2, and the upper leather 2 consists of an outer upper leather 4 and a waist back 5 superimposed on the back side thereof. Further, an arch cushion 13 is provided on the inner arch of the shoe 2, and an insole 12 is arranged on the surface of the arch cushion 13. The arch cushion 13 is made of a material such as hard sponge, cork, or felt so as to have a height and elasticity sufficient to support the inner arch of the foot.

On the inside surface of the arch cushion 13, an arch support 3 that covers the entire arch cushion 13 is attached to the outer upper leather 4.
The arch support 3 is sandwiched between the arch support 3 and the back of the waist 5, and is arranged so as to rise upward from the arch cushion 13, and the rear end portion of the arch support 3 is built into the heel portion of the upper 2. It is overlapped with a hard moon-shaped core 6. This arch support 3 is made of a material that softens when heat or chemicals are applied and hardens when they are removed, such as a molded synthetic resin board, compressed scrap leather, or any other suitable material during the armor manufacturing process. It is sometimes inserted between the upper leather 4 and the back of the waist 5, and is built in by the upper leather 2.

Further, an insole 9 is provided on the lower side of the insole 12,
A shank 10 made of steel, for example, is built into the arch of the lower part of the foot, and around the shank 10 there is a midsole 8.
are arranged, and an outsole 7 is provided at the bottom of the shank 10 and the midsole 8. In addition, 11 is a heel core formed in the outsole 7, 14 is a cushion material sewn to the opening edge of the shoe 1, and the sponge is wrapped in soft leather.

In the above embodiment, an example was shown in which the arch support 3 and the moon-shaped core 6, which were molded separately, were used as the core material built into the upper leather 4, but the invention is not limited to this. Core material may also be used.

Since the present invention is configured as described above, the part from the quarter part of the upper 2 to the circumference of the heel is hardened by the built-in arch support 3, and the arch cushion 1
The resistance force against the pressing force from the inside to the outside of the arch of the upper 2 caused by the deformation of the upper 2 can be increased. Therefore, every time weight is applied to the foot, the arch 13 is created by the inner arch of the foot.
Even if the arch support 3 is pressed, the lower part of the arch support 3 presses the entire inner surface of the arch cushion 13 to prevent the arch cushion 13 from deforming so as to be pushed inward, and the upper part of the arch support 3 This presses the inner surface of the foot and prevents wrinkles from forming on the upper leather 2.

Furthermore, since the shank 10 is built into the arch of the sole, the resilience of the sole against bending is increased, and the arch cushion 13 is supported from below, allowing the arch cushion 13 to support the inner arch of the foot. Since it strengthens the ability to push up, the effect of preventing arch decline is further increased.

As described above, according to the health shoe of the present invention, the part of the arch support that covers the arch cushion prevents deformation of the arch cushion and supports the navicular bone of the foot from lowering, and also supports the arch cushion. The part of the foot that rises above the arch cushion presses the medial surface of the foot above the medial arch portion of the foot to prevent the medial surface of the arch from being pushed inward. Therefore, even if the foot continues to bear weight for a long time, the arch can be prevented from deteriorating. Therefore, foot fatigue, foot pain, and foot deformity can be prevented, and foot health can be maintained.
