Description

  The present invention relates to a sandal having an insole, which reduces the burden on a leg during walking and reduces fatigue of a foot.

  Currently, the midsole of sandals and shoes that are generally marketed has the midsole that matches the shape of the sole of sports shoes, etc., and the midsole where the arch part is raised according to the shape of the arch Some have. These have a function of reducing the burden on the foot and helping the formation of the arch. With regard to sandals, some of the so-called healthy sandals generally have a protrusion on the center of the sandal to stimulate the sole. In the conventional sandals, the burden on the foot is reduced only at the arch portion and the portion in front of the arch.

  There are also sports shoes having an air cushion on a bottom portion, for example, a heel portion, in order to absorb a shock to a foot. Sandals and shoes having such a function are commonly found in sports shoes and the like.

  Conventional sandals have problems such as impact on the foot and fatigue of the foot due to the thin and hard insole. In addition, sandals having a function of absorbing an impact have a problem in that the manufacturing cost increases.

  In order to solve the above-mentioned problem, the present invention provides an outer cover for covering the surface of the foot, a sandal consisting of an insole on which the sole is placed, and a sole, in which the cushion material is covered with an epidermis to form the insole. The bottom is divided into two parts, a front part of the midsole and a rear part of the midsole. The front part of the midsole and the rear part of the midsole are fixed before and after the arch part of the bottom of the sandals. A sandal is provided.

  Further, in the sandal of the present invention, it is preferable that the front part of the midsole and the rear part of the midsole are formed according to the shape on which the sole is placed.

  Further, in the sandals of the present invention, it is preferable that the total area of the front part of the midsole and the rear part of the midsole is 70% or more of the area of the bottom of the sandals.

  The sandal of the present invention is a sandal composed of an outer skin covering the surface of the foot, an insole on which the sole is placed, and a sole, wherein the cushion material is covered with the epidermis to form the insole, and the insole is located in front of the insole. The front part of the midsole and the rear part of the midsole are fixed to the front and rear of the arch part of the bottom of the sandal, so that the front part of the midsole and the rear part of the midsole are fixed to the sole. And the blood circulation becomes smooth by the stimulating effect of pressing the sole of the foot, and the fatigue of the foot can be reduced.

  In addition, since the insole is divided into two parts, by changing the arrangement according to the size, it is possible to use one kind of insole for a plurality of sizes. The material can be reduced, and the cost can be reduced. Further, being able to support a plurality of sizes with one kind of insole means that it is also possible to support a plurality of kinds of sandals, which has an effect of further cost reduction.

  The front part of the midsole and the rear part of the midsole are formed according to the shape of placing the sole, and the combined area of the front part of the midsole and the rear part of the midsole is the sandal. When the area is 70% or more of the area of the sole, the shock absorption to the sole becomes more effective.

  Hereinafter, an embodiment of the sandals of the present invention will be described with reference to the drawings. Embodiments include gentleman's sandals, children's sandals, women's sandals, and the like. Here, description will be made using women's sandals.

  FIG. 1 is a perspective view showing an embodiment in which the midsole of the present invention is used for a women's sandal 1, and FIG. 2 is a sectional view of the women's sandal 1. Although the embodiment shows women's sandals, the present invention is not limited to this, and may be men's sandals or children's sandals.

  A cushion material 5 is formed by cutting a urethane sponge having a thickness of 3 mm by dividing the urethane sponge into a front portion 2 and a rear portion 3 of the midsole, the shape being adapted to the shape on which the sole is to be placed. The combined area of the front part 2 of the midsole and the rear part 3 of the midsole is formed so as to be 70% or more of the bottom 4 of the sandals. A part of a surface of the cushion material 5 that contacts the sole and a part of a surface to which the bottom 4 of the sandal adheres are covered with leather as a skin 6 to form the front part 2 of the midsole and the rear part 3 of the midsole. Is done.

  The front part 2 of the midsole and the rear part 3 of the midsole covered with the skin 6 are positioned at two places, a front part and a rear part, with respect to the arch of the bottom 4 of the sandals, and the adhesive is used to position the sandal. Secure to the bottom 4 of the sandals. In order to simplify the positioning, a mark for bonding the cushion material 5 may be provided on the bottom 4 of the sandal in advance. The women's sandals 1 are manufactured using the outer skin covering the sole 4 and the foot surface of the sandals thus formed.

  Examples of the cushion material 5 at the midsole include a material having cushioning properties such as a sponge, urethane foam, urethane sponge, silicone, EVA (ethylene vinyl acetate copolymer resin) foam and the like. The skin 6 covering the surface is not limited to leather, and may be a woven or non-woven fabric other than genuine leather or synthetic leather.

  The reason why the insole is attached to the front portion and the rear portion is a portion of the sole where a load is applied, particularly for increasing the pressing effect.

  Also, when implemented with women's sandals as in the present embodiment, unlike the conventional insole with no design, the divided insole is covered with a skin of a different color and design from the bottom 4 of the sandals, By putting stitches and the like on the surface of the garment, the design can be enhanced, and when sold at a store, it can be more appealing to consumers when arranged along with other sandals.
