Description

[Detailed Description of the Invention] The present invention relates to an insole for sports shoes that has improved heat retention and sweat absorption.

The insole for sports shoes according to the present invention will be explained based on an example. As shown in Figs. The sweat absorbent material 3 is formed by integrally weaving the layer 2 and the sweat absorbent material 3, and this sweat absorbent material 3 is placed on a foam sheet 4 such as polyethylene foam, and as shown in FIG. As shown in FIG. 3, these two parts 3 and 4 are integrated and then punched out in the shape of the sole of the foot to form an insole as shown in FIG. 4.

Here, the upper layer contains non-water-absorbing fibers, such as polyvinyl chloride-based, polyester-based, nylon-based, polypropylene-based, vinylidene, or vinylon fibers, and the lower layer contains fibers with good water absorption properties. For example, fibers such as Kyupura, rayon, cotton, water-absorbing nylon, and acrylic are appropriately selected and used.

In addition, between the upper layer 1 and the lower layer 2, in order to further improve the comfort of wearing, there is an intermediate layer 6 in which a breathable core material such as non-woven fabric is inserted.

As described above, the insole of the present invention consists of the foam sheet 4 in which the upper layer 1 is made of a non-water-absorbent fabric and the lower layer 2 is made of a highly water-absorbent fabric, so that sweat generated from the soles of the feet is absorbed. It passes through this upper layer 1 and is adsorbed to the lower layer 2, so that the surface of the upper layer 1, that is, the surface that touches the sole of the foot, always feels dry, and in combination with the heat retention of the foam sheet 4, it provides good comfort. We can provide insoles.

In addition, since the upper layer 1 and the lower layer 2 are integrally woven into a sweat-absorbing material 3, it can be integrated with the foam sheet 4 and punched into the shape of the sole of the foot simply by applying pressure with the press die 5 under heating. , an adhesive is not required, the manufacturing process is simple, and it is possible to economically provide a highly durable insole in which the upper layer 1 and the lower layer do not separate.
