Description

[Detailed explanation of the invention] This invention relates to insoles for athletic shoes, such as tennis shoes and track and field shoes. The upper surfaces of the shoe are adapted to the shape of the user's heel and held in a deformed manner to reliably support the foot in a predetermined position of the shoe to facilitate exercise and improve wearing comfort.

Hereinafter, embodiments of this invention will be described based on the drawings.

Reference numeral 1 denotes an insole body that is placed on the inner sole of the shoe, and has raised peripheral edges from the arch to the heel, a recess 2 on the upper surface of the heel, and a raised portion on the upper surface of the finger joint. It has a structure in which a top material 1b such as a hygroscopic cloth is attached to the surface of a plate-like base material 1a made of a foamable synthetic resin having elasticity, such as polyurethane foam.

The inner thick part of the arch part is formed to be considerably higher than the outer thick part, and the height near the center of the arch part is made to be slightly higher than the height of the depression 2 of the heel part. In addition, a plurality of protrusions 4 are protruded from the lower surface of the base material 1a of the main body extending from the arch of the foot to the heel, and a deformation of the heel is provided near the center of the base material 1a in accordance with the shape of the user's foot. A circular groove 5 is provided to facilitate the fitting, and a fitting groove 6 is formed on the outer surface of the thick peripheral portion of the base material 1a. Incidentally, although not shown in the drawings, good air permeability can be achieved by appropriately forming small holes penetrating the base material 1a at appropriate locations.

Reference numeral 7 denotes a plate-shaped formwork member attached to the lower surface of the main body 1 from the arch to the heel, and is made of a hard synthetic resin plate such as polypropylene or a hard plate material such as an aluminum plate. An insertion hole 8 corresponding to the protrusion 4 into which these can fit is bored, and an edge that can fit into the fitting groove 6 along the periphery of the formwork member 7 excluding the tip edge. 9 are erected, and furthermore, a plurality of notches 10 are made with gaps in the width direction toward the rear from the tip edge of the arch. In addition, although not shown, a large number of small holes passing through the formwork member 7 may be bored at appropriate locations to reduce the weight, or projections with pointed tips may be provided at appropriate locations on the lower surface of the formwork member 7. It is possible to improve the anti-slip effect. Moreover, instead of drilling the insertion hole 8 in the lower surface of the formwork member 7, the lower ends of the opposing edges 9 of the formwork member 7 may be connected by two or three connecting plates (not shown). An opening corresponding to the insertion hole 8 may be provided. Furthermore, if the edge 9 is formed slightly thicker,
It is also possible to eliminate the connecting member.

Next, the function of the insole of the above embodiment will be explained.

The insertion hole 8 of the mold member 7 is fitted into the protrusion 4 of the insole main body 1, and the edge 9 is fitted into the fitting groove 6, so that the mold member 7 is attached to the lower surface of the main body 1 from the arch of the foot to the heel. Insert it into the shoe and spread it over the entire inner sole.

When used in this state in the same way as a conventional insole, the base material 1a of the main body 1 is made of elastic foam, and the lower surface and peripheral edge of the base material 1a from the arch of the foot to the heel are Since the outer surface of the thick portion is held by the formwork member 7, it is deformed and maintained in a deformed state to closely fit the shape of the user's foot within a short period of time after the start of use.

Further, since a plurality of notches 10 are made in the arch portion of the formwork member 7, it has good flexibility and is easy to walk on.

As explained above, the insole of this invention is
During use, the insole deforms and retains its shape to adapt to the shape of the user's foot, and at least the area around the heel of the foot is supported by the molding member, so even during strenuous exercise, the insole remains in place within the shoe. Since the position of the foot does not change and the bones of the foot are properly adjusted to a state suitable for exercise, it is possible to fully demonstrate various exercise abilities, and is especially suitable as an insole for athletic shoes. In addition, as shown in the example, if a raised part corresponding to the ball of the toe is provided, the insole will adapt to the shape of the user's foot, making it extremely comfortable to wear. Since the base material of the insole is made of foamable synthetic resin, it is light and has good cushioning properties, making it easier to walk and reducing fatigue.

Claims (1)

[Scope of utility model registration request] It consists of an insole body that is placed on the inner sole of the shoe, and a formwork member that is attached to the lower surface of the insole body that extends from the arch to the heel. It is constructed by pasting a hygroscopic top material on the surface of a foamable synthetic resin plate-like base material with elasticity, which has a high and thick heel part and a depression on the upper surface of the heel part, and the formwork member is made of the above-mentioned material. An insole for shoes, characterized in that it is molded from a hard plate having an edge corresponding to the thick side wall of the main body.
