Description

[Detailed description of the invention] This invention relates to shoes suitable for sports involving soccer such as soccer, rugby, and American football.The purpose of this invention is to maintain the inward bending of the sole during running and The object of the present invention is to suppress the outward bending of the sole of the shoe (outward bending) to reduce the loss of kick ball energy, increase the kick ball speed, and improve the directionality.

In sports such as soccer, rugby, and American football, in addition to running motions, kicking of the ball is required during the competition, but with conventional shoes, the soles of the shoes bend inward to adapt to the movements of the feet while running. However, when kicking a ball with the toe, the sole of the shoe bends outward in the opposite direction to when running, causing a loss of energy and reducing the speed of the kicked ball. Because it is easy to lose direction, experienced players put effort into their toes when kicking to reduce the bending of the sole of their shoes, leading to faster fatigue.

Therefore, in order to limit the bending of the sole and increase kicking power, it is possible to add rigidity to the sole, but increasing the rigidity deteriorates the adaptability with the foot and hinders running, making the shoe difficult to run in. As a result, he was unable to satisfy both running and kicking at the same time.

Therefore, this invention provides a soccer shoe that does not inhibit the inward bending of the sole during running and is capable of suppressing the bending of the sole during kicking, and an embodiment thereof will be explained with reference to the drawings. .

That is, a flexible midsole 1 is formed of rubber, synthetic rubber, etc., and the midsole is made of carbon fiber, silicon carbide fiber, Kevlar fiber, alumina fiber, etc. having a high elastic modulus and tensile strength, for example, in the entire length direction of the upper surface. A protective layer 6 is formed by covering the upper surface or both sides of reinforcing fibers 2 having a length that extends to approximately the entire length of the sole 1 with a flexible material, and the tip 3 is placed at the toe portion of the insole and the rear end 4 is placed at the heel. This soccer shoe is characterized in that the insole is adhered to the upper surface of the outsole 5 with the insole left free except for the front and rear ends.

In addition, since the above-mentioned insole 1 has a protective layer 6 formed by covering the upper surface of the reinforcing fibers 2 or the entire front and back surfaces with a soft material, this prevents the reinforcing fibers from coming loose and mutual friction, and improves flexibility. It is preferable to cover with a protective layer 6 that retains flexibility even after curing, such as a polyurethane elastomer or rubber latex, which does not hinder the protection.

In this invention, as mentioned above, reinforcing fibers 2 are arranged on the upper surface of the insole 1, and the tips 3 of the reinforcing fibers are placed at the toe part of the insole 1.
Since the rear end 4 is fixed to the heel and the parts other than the front and rear ends are separated from the insole 1, the tension of the reinforcing fibers 2 does not act at all when the sole bends inward. Therefore, there is no risk of interfering with the inward bending action of the sole during walking or running.

When playing soccer, the tip 3 and rear end 4 of the reinforcing fibers 2 are fixed to the toe and heel of the midsole 1, so even if you try to bend the sole outward, the tension of the reinforcing fiber 2 acts and causes it to bend outward. Prevents bending. Therefore, it is not necessary to apply force to the toe of the shoe to reduce the outward bending of the toe during the kick, and the loss of kick ball energy is reduced, the speed of the kicked ball increases, and the target direction is also improved. do.

In this way, it is possible to provide shoes suitable for sports involving soccer that cause less foot fatigue.
