In the shoe attachment product 100, the thickness τ2 of a rear side 120 of the shoe attachment product in the attached state is smaller than the thickness τ1 of a front side 110 of the shoe attachment product.SELECTED DRAWING: Figure 2

Description

The present invention relates to a shoe attachment product that is attached to a shoe.

Shoes in which a protrusion is provided on at least one side of the heel portion or the other side portion of the heel portion of the back skin of the instep portion are known (see, for example, Patent Document 1).

In such shoes, the heel of the foot does not easily come off during walking, and it is easy to walk.

Japanese Unexamined Patent Publication No. 2011-041590

By the way, although various shoes are sold, it is difficult to select the most suitable shoes in consideration of the size of the foot, and many users suffer from hallux valgus.

However, in the conventional shoes described above, it is not always possible to expect the effect of preventing hallux valgus and the like.

Then, the present inventor has come up with the idea that it is desirable to prevent hallux valgus and the like by a shoe attachment product that can be easily attached to a shoe on the market, not by the shoe itself.

An object of the present invention is to provide a shoe attachment product which can be expected to have an effect of preventing hallux valgus and the like in consideration of the above-mentioned conventional problems.

The first invention is a plank-shaped shoe attachment product attached to the rear side of the outer sole of a shoe.
It is a shoe attachment product characterized in that the thickness of the rear side in the mounted state is smaller than the thickness of the front side.

The second invention is the shoe attachment product of the first invention, characterized in that the plank shape in the bottom view is a horseshoe shape.

INDUSTRIAL APPLICABILITY According to the present invention, it is possible to provide a shoe attachment product that can be expected to have an effect of preventing hallux valgus and the like.

Perspective view of the shoe attachment product according to the embodiment of the present invention. Right side view of the shoe attachment product according to the embodiment of the present invention. Bottom view of the shoe attachment product according to the embodiment of the present invention Bottom view of the shoe attachment product according to the embodiment of the modified example of the present invention.

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

The shoe attachment product 100 is an example of the shoe attachment product in the present invention, and the shoe 500 is an example of the shoe in the present invention.

First, the shoe attachment product 100 of the present embodiment will be specifically described with reference to FIGS. 1 to 3.

Here, FIG. 1 is a perspective view of the shoe attachment product 100 of the embodiment of the present invention, FIG. 2 is a right side view of the shoe attachment product 100 of the embodiment of the present invention, and FIG. 3 is a right side view of the shoe attachment product 100 of the present invention. It is a bottom view of the shoe attachment product 100 of the embodiment.

FIGS. 1 to 3 show a shoe attachment product 100 attached to the shoe 500 for the left foot.

Of course, the following description of the shoe attachment product 100 attached to the shoe 500 for the left foot also applies substantially to the shoe attachment product 100 attached to the shoe 500 for the right foot.

The shoe 500 is a men's shoe made of synthetic leather. However, the shoes 500 may be women's shoes made of artificial leather, athletic shoes made of cloth, or slippers made of resin.

The outer sole 510 of the shoe 500 is gently curved on the front side and substantially flat on the rear side protruding downward. However, the shoe 500 may be generally gently curved or may be generally substantially flat.

The shoe attachment product 100 is a plate-shaped product that is attached to the rear side of the outer sole 510 of the shoe 500.

The thickness of the plate shape is not uniform as described later, but may be uniform.

The shoe attachment product 100 is formed by laminating and laminating a plurality of synthetic leathers. However, the shoe attachment product 100 may be formed by injection molding a resin.

The shoe attachment product 100 is attached to the shoe 500 by using an adhesive. However, the shoe attachment product 100 may be attached to the shoe 500 by using an adhesive tape, by using a hook-and-loop fastener, or by using a screw. ..

The shoe attachment product 100 is attached only to the rear side of the outer sole 510 of the shoe 500. However, the shoe attachment product 100 may be attached not only to the rear side of the outer sole 510 but also to the front side of the outer sole 510.

The thickness τ2 of the shoe attachment product rear side 120 in the mounted state is smaller than the thickness τ1 of the shoe attachment product front side 110.

Thanks to this difference between thickness τ1 and thickness τ2, on the sole of the foot from slightly behind the arch of the foot to the heel, the weight is outlined by arrow A and then downwards. It will be easier to hang. Therefore, since the foot inside the shoe 500 settles on the rear side and does not easily shift to the front side, the effect of preventing hallux valgus and the like can be expected.

The shoe attachment product 100 is slightly tilted so as to rise diagonally from the rear side to the front at a portion corresponding to the sole of the foot portion slightly in front of the heel portion. Therefore, not only is it easier for the body weight to be applied downward after being substantially indicated by the arrow A, but also the wear of the outer sole 510 of the shoe 500 during walking is suppressed.

Next, the shoe attachment product 100 of the present embodiment will be described more specifically with reference to FIG. 3.

The plank shape in bottom view is a horseshoe shape.

As shown in FIG. 4, which is a bottom view of the shoe attachment product 100 according to the embodiment of the modified example of the present invention, the plank shape in the bottom view may be an inverted horseshoe shape.

Since the shoe attachment product bay-shaped entrance 130 is formed in the center of the plate shape in the left-right direction, not only is it difficult for foot fatigue to occur due to the product weight, but also the increase in product cost is suppressed. To.

Shoe attachment product The bay-shaped entrance 130 does not bear weight, and the sole of the foot from a little behind the arch of the foot to the heel can easily bear weight, so the core of the foot is firmly supported by the horseshoe shape. Be done. Therefore, the weight is applied to the left and right sides of the shoe attachment product bay-shaped entrance 130 in a well-balanced manner in the downward left direction and the downward right direction, respectively, which are outlined by arrows B and C, so that the standing posture during walking is stabilized and optimized. You can expect the effect to be achieved.

The shoe attachment product of the present invention can be expected to have an effect of preventing hallux valgus and the like, and is useful for the purpose of using the shoe attachment product to be attached to shoes.
