shoe Fig. 1 shows the appearance of a shoe 10 according to an embodiment of the present creation. The shoe 10 of this embodiment is composed of an upper 1 and a sole 2.

The upper 1 is used to cover and protect the foot. The material of the shoe upper 1 is not particularly limited. For example, leather such as natural leather, synthetic leather, and artificial leather, fabric using natural fiber or chemical fiber, rubber, etc. may be mentioned.

Sole FIG. 2 is a top view of the sole 2. Fig. 3 is a cross-sectional view taken along the line II-II in Fig. 2.

The sole 2 includes a first area 31, a second area 32, and a third area 33. In the longitudinal direction Y, the first area 31 supports the front side of the sole, the second area 32 supports the middle including the sole, and the third area 33 supports the rear side of the sole.

The sole 2 has an inner sole 5 and an outer sole 6. In addition, the sole 2 of the present embodiment has a heel 7 on the rear side in the longitudinal direction Y.

Insole The inner sole 5 is arranged on the outer sole 6. The inner sole 5 has air permeability and water absorption.

The inner sole 5 of this embodiment has a base layer 51, a resin layer 52, and a printing layer 53. Each layer constituting the inner sole 5 has air permeability and water absorption.

The base layer 51 is a support body of the inner sole 5 and is arranged on the outer sole 6. The base layer 51 having air permeability and water absorption is not particularly limited. For example, non-woven fabrics, woven fabrics, and the like can be used.

The resin layer 52 is disposed on the base layer 51. The resin layer 52 protects the surface of the base layer 51 and promotes the formation of the printed layer 53. As the resin that can be used for the resin layer 52, for example, polyurethane (PU), ethylene-vinyl acetate copolymer (EVA), etc. may be mentioned.

The air-permeable and water-absorbent resin layer 52 can be formed by forming a resin film on the base layer 51 and foaming, for example, a porous resin film having continuous voids in the thickness direction.

In addition, the resin layer 52 can also be formed using, for example, high air permeability and water absorption, specifically, a resin having a high water vapor transmission rate. Even if the resin has a low water vapor transmission rate, after forming the resin film on the base layer 51, through holes are provided on the entire surface of the inner bottom 5 with a needle or the like to impart air permeability and water absorption.

The printing layer 53 is provided on the resin layer 52. According to the printed layer 53, the design feeling of the inner sole 5 can be enhanced by coloring the surface of the inner sole 5 to impart a leather texture or the like. The printing layer 53 can be formed by printing on the resin layer 52 with ink.

The inner sole 5 of this embodiment has a cushion 4 between the base layer 51 and the resin layer 52. The cushion 4 is arranged inside the second area 32 to support the sole of the foot.

The cushion 4 has air permeability, water absorption and elasticity. In this embodiment, as such a cushioning pad 4, a polyurethane-made pad in which through holes 41 are provided in the thickness direction of the inner sole 5 is provided. In addition, the material of the cushion pad 4 is not particularly limited, and a resin-made pad such as silicone or a cotton-made pad can be used.

Outsole The outsole 6 is arranged at the lower part of the insole 5. FIG. 4 shows the surface of the inner sole 5 side of the outer sole 6.

The outsole 6 of this embodiment has four first grooves 61, second grooves 62, third grooves 63 and two fourth grooves 64 on the surface of the inner bottom 5 side. In addition, the outsole 6 has an opening 65 leading to the outside of the shoe 10.

First groove The first groove 61 is provided in the area supporting the heel of the toe in the first area 31 and extends in the width direction X.

The four first grooves 61 are arranged side by side in the length direction Y. In the longitudinal direction Y of each first groove 61, the arrangement interval on the inner side of the foot is smaller than the arrangement interval on the outer side. Therefore, the first groove 61 extends radially from the base of the thumb to the base of the little finger.

Generally, when the foot that touches the ground leaves the ground, the weight moves from the heel to the vicinity of the base of the little finger, and then to the vicinity of the root of the thumb on the inner side of the width direction X. When the body weight moves from the rear side in the length direction Y to the front side, the center in the width direction X does not move, but moves outside the center.

With the aforementioned weight movement, the heel leaves the ground, and the area from the center of the sole of the foot to the base of the toe bends into an arch. The outsole 6 also bends in accordance with the movement of the foot, but the outer sole 6 having the outer arrangement interval d1 of the first groove 61 larger than the inner arrangement interval d2 is easy to bend along the shape of the sole of the foot moving outward.

Since the outsole 6 follows the movement of the foot, the wearer can walk naturally, and a shoe 10 with excellent walking performance can be provided.

Second groove The second groove 62 extends in the length direction Y of the foot. In this embodiment, the second groove 62 is provided at the center of the substantially width direction X and passes through the first area 31, the second area 32, and the third area 33.

The second groove 62 of this embodiment intersects with the four first grooves 61 and the third groove 63 and is in contact with the fourth groove 64. Therefore, the plurality of grooves 61 to 64 communicate with each other through the second groove 62.

Third groove The third groove 63 is provided in the area supporting the heel in the third area 33. The third groove 63 extends in the width direction X of the foot and intersects the second groove 62.

Fourth groove The fourth groove 64 is provided in the area supporting the palm of the foot in the second area 32. The fourth groove 64 is connected to the second groove 62 and the opening 65.

In this embodiment, the two fourth grooves 64 respectively extend from the front side and the rear side of the length direction Y of the second groove 62 toward the outer circumferential surface of the outsole 6 and reach the opening 65. There are two paths to the opening 65 in the front and back, so the ventilation efficiency is improved.

Opening The opening 65 is provided on the outer circumferential surface of the outsole 6. The opening 65 is connected to the fourth groove 64 among the plurality of grooves 61 to 64.

The opening 65 is provided on the inner side in the width direction X of the area supporting the center of the sole of the foot. According to this arrangement, the opening 65 is not conspicuous, and the design of the shoe 10 is not easily damaged. In addition, ventilation on the front side and the rear side in the longitudinal direction Y becomes easy.

heel In order to adjust the height of the heel, the heel 7 is set as required. From the viewpoint of protecting the outsole 6, a harder material than the outsole 6 may be used for the heel 7, for example, TPU (thermoplastic polyurethane).

The above-mentioned shoe 10 is manufactured by the following method. For example, the outer circumference of the upper 1 and the outer circumference of the inner sole 5 are stitched together, and the inner sole 5 provided with the upper 1 is adhered to the grooves 61 to 64 and the outer sole 6 except On the surface other than the opening 65, the heel 7 is adhered to the surface on the opposite side.

The manufacturing method of the shoe 10 is not limited to the above-mentioned method. For example, the upper 1, the insole 5 and the outsole 6 can all be bonded together with an adhesive.

Ventilation The shoe 10 can realize internal ventilation. Hereinafter, the ventilation effect of the shoe 10 will be described.

The air in the shoe 10 flows into the grooves 61 to 64 of the outer sole 6 through the inner sole 5. The grooves 61 to 64 are connected to the opening 65, so while the air is discharged from the grooves 61 to 64 to the outside through the opening 65, the air enters the grooves 61 to 64 from the outside.

In addition, the inner sole 5 also has water absorption, so that water in the shoe 10 can also flow from the inner sole 5 to the outer sole 6 and drain from the outer sole 6 to the outside.

The internal pressure changes according to the movement of the feet during walking, so the grooves 61 to 64 of the outsole 6 can be used as a pump for promoting ventilation.

FIG. 5A shows the outsole 6 when the foot is in contact with the ground. FIG. 5B shows the outsole 6 when the foot is on the ground.

When the outsole 6 is bent in accordance with the movement of the foot stepping on the ground, the first groove 61 is compressed. Through this compression, not only the first groove 61 is in a pressurized state, but also the interiors of the other grooves 62 to 64 leading to the first groove 61 are also in a pressurized state. As a result, through the second groove 62 and the fourth groove 64, the air in the first groove 61 and the third groove 63 is discharged from the opening 65 to the outside.

The outsole 6 having the outer side setting interval d1 of the first groove 61 greater than the inner side setting interval d2 is easy to bend along the shape of the sole, and the first groove 61 is easy to be compressed, so effective pressurization can be achieved.

On the other hand, when the foot completely leaves the ground or the entire foot surface is in contact with the ground and the outsole 6 is flat, the compression of the first groove 61 disappears. The insides of the grooves 61 to 64 are in a decompressed state, so the outside air flows into the first groove 61 and the third groove 63 from the opening 65 through the fourth groove 64 and the second groove 62.

In this way, the shoe 10 of the present embodiment functions as a pump by pressure changes in the plurality of grooves 61 to 64, and repeats the removal and supply of air during walking. It is possible to provide a comfortable shoe 10 capable of improving the air permeability in the shoe 10 and reducing the stuffy feeling.

In addition, the arrangement interval d1 on the outer side of the first groove 61 is greater than the arrangement interval d2 on the inner side, so the outsole 6 is easily deformed following the movement of the foot during walking. It is possible to provide shoes 10 that can walk naturally and have excellent walking performance.

The preferred embodiments of the present creation have been described above, but the present creation is not limited to these embodiments, and various modifications and changes can be made within the scope of the gist.

For example, the above-mentioned number and size of the grooves 61 to 64 and the lengths of the intervals d1 and d2 of the first grooves 61 are examples, and can be changed according to the size of the shoe 10 and the bending performance of the outsole 6.

In addition, the position of the opening 65 may be on the rear side in the longitudinal direction Y. When walking, the rear side is separated from the ground, so it is easy to prevent water from penetrating into the shoe 10 from the outside through the opening 65. In the case of a shoe 10 having a high heel 7, it is particularly difficult to be immersed in water, so the opening 65 on the rear side is preferable.

In addition, the fourth groove 64 may not be passed through, but the first groove 61 is directly connected to the opening 65. It is also possible, for example, that the four first grooves 61 extend inward in the width direction X, and openings 65 are respectively provided at positions extending to the outer circumferential surface of the outsole 6, and each opening 65 is opposite to each first groove 61 connection.

Similarly, the second groove 62 and the third groove 63 can also be directly connected to the opening 65. For example, the second groove 62 extends in the length direction Y, the third groove 63 extends in the width direction X, and openings 65 are respectively provided at positions extending to the outer circumferential surface of the outsole 6, and each opening 65 is connected to the second groove 62 and the third groove 63 respectively.
