[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe insole which is free from stuffiness, easy to walk, and easy to exercise.

[0002]

2. Description of the Related Art When shoes are worn for a long time,
Hot or humid air filled the shoes, resulting in foot stuffiness and pain near the toes, often hindering walking and exercise. Therefore, various ingenuity shoe insoles have been conventionally proposed. For example, a fabric surface of an insole made of a multilayer body of a fabric and a foam is used as a foot contact surface, and a groove communicating with each other is formed in the foot contact surface, or a groove penetrates vertically at an appropriate position of the laminate. A structure has been proposed in which a plurality of ventilation holes are provided, and a fabric having good water absorption is used to absorb sweat from feet and socks.

[0003]

However, in the shoe insole as described above, in which the grooves that communicate with each other are recessed in the foot contact surface, the sole of the foot contacts the upper surface at the recessed portion of the groove. Therefore, sweat on the soles is not absorbed by the fabric in that part, the feet are not sticky, and the discomfort cannot be sufficiently eliminated, and a plurality of ventilation holes vertically penetrating into appropriate portions of the laminate are provided. The one provided does not have an exhaust groove, so it cannot discharge hot air or moisture, and the one using a fabric with good water absorption on the foot surface absorbs sweat at the initial stage of wearing, and Although the pleasure is not so much generated, when the absorption amount becomes saturated, sweat cannot be absorbed thereafter, and humidification occurs. In addition, since all of the insoles are not devised in the vicinity of the toes, it has not been possible to avoid pain caused by long-time walking or exercise. SUMMARY OF THE INVENTION An object of the present invention is to provide a shoe insole which solves all of the above-mentioned conventional disadvantages.

[0004]

The present invention comprises a laminate (4) in which a cloth (1), an open-cell foam (2) and a non-woven fabric (3) are sequentially laminated from an upper layer to a lower layer. When the foot is placed on the lower surface (5) of the body (4), between the toe and the ball portion (6), between the inner ball portion and the outer ball portion (7), and above the inner foot portion The peripheral part (8) is connected to the parts corresponding to the division parts (10) and (10) from the middle of the upper peripheral part (8) to the lower peripheral part (9) of the inner whip, respectively. Groove (11) is recessed,
The groove (11) has a plurality of holes (12), (12),.
Are vertically penetrated, and are formed so as to be thinner from the slightly forward portion (13) of the groove (11) at the portion (6) between the toe and the ball portion toward the tip portion (14). And a groove (1) in a portion (6) between the toe and the ball portion.
1) is partially open toward the tip (14) (1).
5) It features a sock insole. Here the toes are
Used in the concept including from the thumb to the fifth finger, and the ball part,
The concept includes an inner ball portion and an outer ball portion.

As the non-woven fabric (3), a polyester-based or polyamide-based non-woven fabric is usually used, and after press molding or the like for forming a desired shoe insole shape, the shape can be maintained as it is. Polyurethane foam, ethylene-vinyl acetate copolymer foam, or the like is used as the foamed foam (2), and the fabric (1) is obtained from a polyester-based flocculent that causes a capillary phenomenon and has a high water absorption rate. A woven fabric is used.

[0006]

[Operation and Effect] The sole of the shoe according to the present invention can be used when the sole is in contact with the sole of the shoe and is not stepped on (that is, when the sole of the shoe is not weighed). A groove (11) communicating with each other is formed in a lower surface (5) of a portion where a gap is easily formed between the groove (11) and a plurality of holes (12), (12) When ─── penetrates in the up and down direction, when walking or running, hot air or moisture due to sweat or the like accumulated in the gaps or the like is stepped on (ie, when weight is applied to the shoe insole). Through the plurality of holes (12), (12)}, and is led to the groove (11), and is provided on the side surface of the instep and at the end of the groove (11) at the eyelet for ventilation ( (Not shown), and is discharged to the outside of the shoe from a shoe or the like. In addition, when the shoe insole is trampled in such a process, the portion of the sole where the gap has been formed has more sweat than the other sole, but the fabric has good water absorption. The entire surface comes into contact with (1) to absorb sweat, and then passes through the open-cell foam (2) to reach the non-woven fabric (3), so that the inside of the shoe is always kept in a comfortable state.

In addition, since the portion between the toe and the ball portion (6) is formed thinner toward the tip portion (14),
The space at the toe is widened, the toe is easy to move, the chance of contact with the instep of the part is small, and the pain caused by walking or exercise is reduced. In addition, since this space has a humid place at the back of the shoe, ventilation in the shoe is promoted and stuffiness is reduced. The thinned portion is a toe portion, does not take weight, and does not require cushioning.
The other parts are thicker and have cushioning properties. The cushioning property of the part where the weight is applied is maintained, and the stuffiness of the toes is eliminated, and the stuffiness is reduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A shoe insole according to the present invention shown in FIGS. 1, 2 and 3 comprising a polyester nonwoven fabric (3), an open-cell polyurethane foam (2), and a fabric (1) made of polyester cotton, and its use. The same material is used, and the groove (11) of the shoe insole of the present invention is provided on the upper surface, but the holes (12) and (12) ─── which penetrate vertically do not have the shoe insole. Tested in contrast. In this case, the following results were obtained by using the test condition for seven consecutive days for eight hours a day in the summer.
