Abstract

PROBLEM TO BE SOLVED: To wear in with a bare-footed feeling by forming hollow holes at the parts equivalent to the toe part and middle foot part of a foot of an insole and performing formation by the soft material of excellent return so as to fill the entire hollow holes. SOLUTION: For a woman's shoe 1, a planar reinforcing material is fixed to a foot arch part and a heel part which are the second half part of the back surface of the insole 2 and the lower end peripheral edges of a vamp 3 and a quarter 4 are respectively glued and fixed to the back surface peripheral edge of the reinforcing material and the back surface peripheral edge of the insole 2. Further, a front sole 5 is glued and fixed from the back. In order to improve the return of a shoe sole, the hollow holes are formed at the parts equivalent to the toe part 2a and middle foot part 2b of the foot of the insole 2 and the formation is performed by the soft material 8 of the excellent return so as to fill the entire hollow holes. As the soft material 8 of the excellent return to be formed so as to fill the entire hollow holes of the insole 2, the material of latex, rubber and sponge, etc., is selectively used.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to footwear in consideration of ease of wearing various types of footwear such as women's shoes and sandals having an upper, an insole and an outsole.

[0002]

2. Description of the Related Art As a conventional women's shoe for indoor shoes, for example, a plate-like reinforcing material is fixed to an arch portion and a heel portion, which are the rear half of the back surface of an insole, and a peripheral edge of the reinforcing material and the insole. The lower edge of the upper and the waist leather was glued and fixed to the periphery of the back surface, and the outer sole was glued and fixed from behind, and the insole was provided on the upper surface of the insole.

[0003]

However, in the above-mentioned conventional women's shoes, the sole is formed by the insole, the insole and the outsole, and the toes of the foot and the sole corresponding to the midfoot are relatively hard. Because it is formed, for example, if you wear it for a long time as a shoe, the toes and the middle foot equivalent part will return poorly, causing tiredness, and for people who stand for a long time Undesirably puts an excessive burden on the feet.

An object of the present invention has been made in view of the above-mentioned points, and improves the return of a portion corresponding to a toe portion and a midfoot portion of a sole of a shoe so that bare feet can be worn even when worn for a long time. An object of the present invention is to provide footwear that can be worn in a state close to the senses and has a good foot contact.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a footwear according to the present invention relates to a footwear having an upper, an insole, and an outsole. A hole is formed in a portion corresponding to the foot portion, and the hole is formed of a flexible material having a good return so as to fill the entire hole.

Further, the footwear according to the present invention includes latex, rubber, sponge, vinyl chloride copolymer resin, and styrene-butadiene-based flexible material which is formed so as to fill the entire hole of the insole. At least one selected from elastomers, polyolefin-based elastomers, vinyl chloride-based elastomers, acrylate-based elastomers, polyurethane rubbers, silicone rubbers, and silicone resins is used.

Further, the footwear according to the present invention is characterized in that in a footwear having an upper, an insole and an outsole, a punched hole is formed in a toe portion and a middle foot portion of the insole, Holes are also formed in the rear feet of the foot in the insole, and are formed of a flexible material so as to fill the entire hole.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings. 1 is, for example, women's shoes for indoor use. In the present embodiment, the above-mentioned women's shoes will be described, but the type of shoes is not limited to the above-mentioned shoes, but is also applicable to sandal shoes, men's shoes, and the like. As shown in FIG. 1, in this women's shoe 1, a plate-like reinforcing material (not shown) is fixed to an arch portion and a heel portion, which are the rear half portion of the back surface of the insole 2, and the periphery of the reinforcing material is The lower edge of the upper 3 and the lower edge of the quarter 4 are glued and fixed to the peripheral edge of the back of the insole 2. Further, the outsole 5 is glued and fixed from behind. The outsole 5 may be a conventionally used one, but it is preferable that the outsole 5 is not too thick and not too hard in terms of improving the return. An insole 6 is provided on the upper surface of the insole. In this embodiment, no intermediate material is used, but a structure using an intermediate material may be used if necessary.

An important point of the present invention is that in order to improve the return of the sole of the shoe, a hole 7 is formed in a portion corresponding to the toe portion 2a and the middle foot portion 2b of the insole 2, and the hole is formed. The point is that the hole 7 is formed of a flexible material 8 having a good return so as to fill the entire hole 7. Examples of the soft material 8 having good return, which is formed so as to fill the entire hole 7 of the insole 2, include latex, rubber, sponge, vinyl chloride copolymer resin, styrene-butadiene elastomer, polyolefin elastomer, chloride At least one material is selected and used from vinyl elastomers, acrylate elastomers, polyurethane rubbers, silicone rubbers, and silicone resins.

As a criterion for selecting the soft material 8, it is important that the return of the shoe sole is a good casting, but in addition, it has good foot contact, or the soft material 8 is It is important that they adhere well and do not peel off. Further, it is more preferable to select the flexible material 8 having cushioning property, mechanical strength, strong abrasion resistance, excellent oil resistance, excellent heat deterioration property, and excellent weather resistance.

FIG. 5 is a plan view of an insole 2 showing another embodiment of the present invention. Holes 7 are formed in the insole 2 in addition to the parts corresponding to the toes 2a and the midfoot 2b of the foot, and also holes are formed in the rear feet (heel parts of the foot). It is formed of a flexible material 8 so as to fill the whole. In the case where the soft material 8 is formed on the heel portion of the foot of the insole 2 in this way, the return of the foot at this portion is not considered at all, but instead the cushioning property of the heel portion increases, and the comfort is good, It also stimulates the heel of the foot.

[0012]

As is apparent from the above description, the present invention relates to a footwear having an upper, an insole, and an outsole. Since the hole was formed and formed with a flexible material having a good return so as to fill the entire hole, the toe portion and the middle foot portion of the sole of the shoe had good return, and over a long period of time. Even if you are wearing it, you can wear it in a state close to barefoot sensation, and you can get good footwear.

The flexible material having good return formed so as to fill the whole hole in the middle bottom is latex, rubber, sponge, vinyl chloride copolymer resin, styrene-butadiene elastomer, polyolefin elastomer, Since at least one of vinyl chloride-based elastomer, acrylic ester-based elastomer, polyurethane rubber, silicone rubber, and silicone resin can be used, it is easy to manufacture and it can be firmly formed on the periphery of the punched hole. Without peeling
It can be used for a long time, has good cushioning properties,
It has excellent wear resistance, oil resistance, and weather resistance, and can be used for a long time.

Further, in a footwear having an upper, an insole, and an outsole, a punched hole is formed at a toe portion of the insole and a portion corresponding to the midfoot portion of the insole. By forming a hole in the hind foot part and forming it with a flexible material so as to fill the entire hole, the front half of the foot has a good return, the rear half of the foot has increased cushioning, The massage effect on the heel part of the foot is enhanced, and the comfort is further increased.
