Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an insole that can be inserted into and out of a shoe.

[Conventional technology]

Conventionally, insole leather has been attached to shoes to protect the feet from uneven soles and to provide a blind. The insole is made of a thin sheet of leather, synthetic resin, or the like, and has a smooth, flat surface and is hard because it comes into direct contact with the foot.

[Problem that the invention attempts to solve]

However, with these shoes, if your feet develop a bulge such as a corns or wart, or if you get a wound due to an injury, your weight will be concentrated on the wound because the insole is hard and flat. It hurts when walking, making it difficult to walk in them.When the foot expands, it causes a lot of friction, causing pain.Furthermore, people with chronic knee or lower back problems may find it difficult to walk due to the impact of walking. It was hot. In addition, the soles of human feet are not flat, but rather uneven, and only the convex parts contact the insole skin, which can cause foot pain when you first start wearing shoes.If you wear shoes all the time, for example, your pinky toe may become deformed. There were problems such as storage.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention consists of a shoe-sole-shaped thick soft upper sheet made of a highly foamed synthetic resin sheet such as soft polyethylene foam, and a desired thickness that is laminated and fixed on the lower surface of this soft upper sheet. The elastic lower sheet is made of an elastic lower sheet made of polyurethane foam, and the lower surface of the elastic lower sheet is provided with fine cross-cut cuts for excision, and the lower sheet piece is peeled off from the cut at the location corresponding to the wound on the foot. A necessary recess is provided.

[Effect]

According to this invention, since there is a recess in the place where there are scars such as corns or warts, the scar does not receive pressure and there is no pain when walking. Also, since it is a thick foam sheet,
The impact when walking is alleviated, and even when the foot expands, the sheet compresses thinly to accommodate the expansion, so there is no pain. Furthermore, the surface is made uneven to match the shape of the foot, and the entire sole of the foot comes into contact with the sole, which distributes and averages out the body weight.

〔Example〕

An embodiment of this invention will be described based on the accompanying drawings. As shown in FIGS. 1 and 2, the shoe insole of this invention includes a thick, sole-shaped, soft upper sheet 1, for example, about 6 mm thick, made of soft polyethylene foam with a foaming ratio of about 30 times; The elastic lower sheet 2 is made of polyurethane foam with a thickness of about 2 mm and is fixed to the lower surface of the soft upper sheet. A mesh cut 3 is provided,
Peel off a small square piece 4 of the elastic lower sheet 2 from the cut 3 to create a required recess 5 (see Figures 3 and 4) at a location corresponding to a corns, wart, injury, or other wound on the foot. This is what I did.

The soft upper sheet 1 is manufactured by, for example, Sekisui Chemical Co., Ltd.
Made by Softlon (registered trademark), which is a thick material made by laminating and bonding three high-expanded polyethylene foam sheets cross-linked with electron beams with double-sided adhesive tape 6, if compressed for a long time, it will not return even if it gets dented. .

The soft upper sheet 1 can be punched and formed from a single thick sheet from the beginning, and the thickness can be appropriately selected between 5 mm and 10 mm depending on the application. Furthermore, the material used is not limited to soft polyethylene foam.

The elastic lower sheet 2 is bonded to the lower surface of the soft upper sheet 1 with double-sided adhesive tape 6, and the cuts 3 are marked by the grid-shaped cuts 3 with a slight uncut portion 7 on the adhesive tape 6 side. The square-shaped small piece 4 that has been removed is designed not to fall off. When forming the required recess 5, this uncut portion 7 is easily torn off.

When using the insole of the shoe, as shown in FIGS. 3 and 4, a small piece 4 of the elastic lower sheet 2 is placed on the fingertip, etc. at the location corresponding to the wound on the foot such as a corns, wart, or injury. Pick it up and peel it off to make a recess 5, insert it into shoe A, and place your foot on it. Then, the wound on the foot is dented in the direction of the recess 5 and is compressed and helped by the thinner soft upper sheet 1, so that there is no pressure and there is no pain when walking. In addition,
Shoes using this insole are preferably somewhat deep.

In addition, even when the foot expands, the insole of this shoe is soft and the sheet becomes thinner, so it does not apply a large pressure force to the foot, causing pain or poor blood circulation. Even people with chronic illnesses feel less shock when walking on concrete sidewalks, and even ordinary people can
After wearing the shoes for a while, the upper surface of the soft upper sheet becomes uneven so that it fits perfectly to the shape of your feet, so your feet won't slip back and forth or swing sideways.
It also improves blood circulation and prevents your feet from being squeezed by shoes.

〔effect〕

As described above, the shoe insole according to this invention has an approximately 2 mm thick elastic lower sheet laminated and fixed to an approximately 6 mm thick soft upper sheet, and fine checkerboard-like cuts are provided in the elastic lower sheet. If you remove a small piece of the elastic lower sheet from the incision and create a recess in the area corresponding to the wound on the foot, pressure will not be concentrated on the wound, which will relieve pain when walking and make it easier to walk. . In addition to being thick, the soft upper sheet compresses and molds into an uneven surface that fits the shape of your foot after you wear it for a while, so the entire sole of your foot is in close contact, making it easier to walk and evenly distributing your weight. It also has good blood circulation, allowing people with various foot ailments, knee and hip ailments to walk easily.
