Description

The present invention relates to a shoe, and more particularly to a shoe in which an air passage is formed to follow an artery in the sole of the foot in order to prevent air permeability of the surface in contact with the sole of the foot and compression of the artery. ..

Shoes are made up of uppers, soles and shoelaces. Most shoes, such as sneakers, shoes, work shoes, and school shoes (shoe shoes), are surrounded by an upper and form a closed space where air is not circulated when worn by the wearer, resulting in poor ventilation. Poorly breathable shoes produce a lot of unpleasant odors due to sweat secreted from the feet, and bacterial infections cause foot diseases such as athlete's foot. Especially in the summer when a lot of sweat is generated, sweat accumulates in the shoes, which makes the feet stuffy and causes skin damage, and causes athlete's foot due to bacterial growth.

On the other hand, in order to improve the breathability of shoes, various forms of shoes have been developed that can supply and circulate air when the wearer wears the shoes and walks. Korean Registered Patent No. 10-11644463 "Shoes with air circulation function" has an air chamber, a sole with an air passage, an inner cushion that provides restoring force while walking, and an inner. It is equipped with a perforated valve plate located on the cushion and a valve for discharging air to the air chamber. The contaminated air in the shoe due to the contraction and restoration of the inner cushion is expelled into the air chamber of the sole along the air passage. Korean Registered Patent No. 10-0462809 "Shoe Insole for External Air Inflow" is equipped with a check valve and an air pump attached to the inner sole or the insole. By operating the air pump, air is supplied from the rear surface to the front surface of the inner sole along the flow path, and then discharged from the toes through the discharge holes. The check valve allows air to flow only into the shoe through an inflow hole formed on the side of the sole.

The ventilation structure of the shoe as described above is a cause of increasing the manufacturing cost due to the complicated structure of the sole. In addition, there is a problem that the inner cushion and the air pump are built in the sole, which greatly reduces the durability and reliability of the sole. Therefore, there is a demand for shoes that can realize a ventilation function and improve the fit while maintaining durability without significantly changing the structure of the sole.

An object of the present invention is to provide a new shoe that can meet the above requirements.

According to one aspect of the invention, shoes are provided. The shoe according to the present invention includes an upper having a space for accommodating the wearer's foot; and a sole having a shoe insole accommodated in the space, the insole has a surface in contact with the sole of the wearer's foot. However, multiple air passages are engraved on the surface so as to follow the blood vessels on the sole of the foot projected on the sole of the foot.

In the shoe according to the present invention, the sole includes a midsole attached to the lower surface of the upper and an outsole attached to the lower surface of the midsole, and the insole is housed in a space so as to be separated from the midsole. The plurality of air passages are formed so as to be connected to each other.

In the shoe according to the present invention, an air passage that follows the artery of the sole of the foot is formed on the surface of the insole, and a space through which air can flow is formed between the shoe and the sole of the foot, so that sweat, moisture, etc. are effective. Not only can the foot odor be prevented, but also skin damage, athlete's foot, etc. can be prevented, and foot diseases can be prevented. In addition, the air passage during walking of the wearer prevents arterial compression on the sole of the foot, improves blood circulation, improves the health of the foot, improves the fit of the shoe, and tires the sole of the foot. It also has the effect of greatly improving the functionality and practicality of shoes.

Other objectives, specific advantages and novel features of the invention will become clearer from the following detailed description and preferred embodiments associated with the accompanying drawings.

Hereinafter, preferred embodiments of the shoes according to the present invention will be described in detail with reference to the accompanying drawings.

First, FIG. 1 shows sneakers as an example of shoes according to the present invention. Referring to FIG. 1, the shoe according to the present invention is composed of an upper 10 that surrounds and accommodates the wearer's foot, and a sole 20 that is attached to the lower surface of the upper 10. The upper 10 maintains the appearance and shape as the upper part of the shoe, and serves to protect the instep and joint parts. The upper 10 can be made of a material such as leather, artificial leather, or synthetic fiber by forming a space 12 for accommodating the wearer's foot.

The sole 20 is composed of a midsole (Midsole: 22), an outsole (Outsole: 24), and an insole 26 at the lower part of the shoe. The outsole 24, midsole 22, and insole 26 can be made of rubber, synthetic rubber, flexible synthetic resin, or the like. The midsole 22 can be attached to the lower surface of the upper 10 by sewing or adhering an adhesive. The midsole 22 is a sandwich-like portion between the outsole 24 and the insole 26, and acts as a buffer that absorbs and disperses the impact applied to the foot during walking and running. The outsole 24 plays a role of preventing slipping and giving a sense of security by the pattern (Patten) when walking and exercising at a portion in contact with the ground. The outsole 24 can be attached to the lower surface of the midsole 22 by adhering an adhesive. In some embodiments, the midsole 22 can be configured integrally with the outsole 24.

The insole 26 is often called an inner sole because it plays a role of preventing foot fatigue and odor and athlete's foot caused by sweat at a portion of the inner sole of the shoe that can be separated by contacting the shoe. The insole 26 has a tip 26a adjacent to the toes, a rear end 26b adjacent to the heel, an edge 26c connecting the tip 26a and the rear end 26b, and a surface 26d in which the sole 2 contacts.

With reference to all of FIGS. 1 to 4, a plurality of air passages 28 are inscribed on the surface 26d so as to follow the arteries 4 on the sole 2 or the sole projected on the surface 26d. The air passages 28 are formed on the surface 26d so as to be connected to each other. Each end of the air passage 28 adjacent to each of the tip 26a, the trailing end 26b and the edge 26c is closed. The air passage 28 is formed on the surface 26d in the form of a channel or a groove to form a space that allows air flow when in close contact with the sole 2. In some embodiments, the air passage 28 can also be formed to follow the instep artery projected onto the surface 26d along with the sole artery 4. As shown in FIG. 4, the cross section of the air passage 28 can be formed into various shapes such as a quadrangle, a semicircle, and a trapezoid.

In the shoe according to the present invention having such a configuration, air can flow through the air passage 28 forming a space between the shoe and the sole 2, and sweat, moisture, etc. are effectively removed. Not only can it prevent odors, but it can also prevent skin damage and water bugs caused by sweat and moisture, and prevent foot diseases.

On the other hand, when the air passage 28 cannot follow the artery 4 on the sole of the foot and is formed so as to be offset from the artery 4 on the sole of the foot, the artery 4 on the sole of the foot during walking of the wearer is compressed by the air passage 28. There is a risk of impairing blood circulation, reducing the fit of the shoes, and increasing the degree of fatigue of the sole 2. The shoe according to the present invention does not press the artery 4 on the sole of the foot by the air passage 28 formed so as to follow the artery 4 on the sole of the foot on the surface 26d of the insole 26 when the wearer is walking. Therefore, the blood circulation of the sole 2 can be improved, the health of the foot can be improved, the fit of the shoe can be improved, and the degree of fatigue of the sole 2 can be reduced.

The examples described above merely describe preferred embodiments of the present invention, and the scope of rights of the present invention is not limited to the described examples, and the technical idea and patent of the present invention. Within the scope of the claims, various modifications, modifications or substitutions may be made by those skilled in the art, and such embodiments should be understood as belonging to the scope of the present invention.
