Athletic shoe

Abstract

An athletic shoe including: an interior member; and a loop-shaped wrap, wherein the wrap includes: a heel portion covering a part of a calcaneal bone; a band-shaped and / or cord-shaped twisted portion continuous with a front end portion of the heel portion on medial side, extending toward under a foot sole while twisted on medial side; a medial bottom portion continuous with a front end portion of the twisted portion, extending along a medial side portion to a ball of a big toe under the foot sole; and a band-shaped and / or cord-shaped diagonal transverse portion continuous with a front end portion of the heel portion on lateral side, covering a portion of a cuboid bone and / or a tuberosity of a fifth metatarsal bone, and further extending across an instep diagonally forward so as to cover an upper surface of the big toe and a side surface of the ball.

Description

TECHNICAL FIELD[0001]The present invention relates primarily to indoor shoes such as those for volleyball or basketball.BACKGROUND ART[0002]In recent years, with the change in the spiking form in volleyball, there is a significantly increased load on a side brake on the front foot during a jump (i.e., the foot that is placed in front of the body in the forward direction immediately before takeoff). Also in basketball, a violent direction-changing move referred to as “Eurostep” is becoming common.[0003]With the conventional shoe structure, due to the insufficient rigidity of the upper, in practice, a phenomenon called “lateral bulging” may occur, where the foot laterally slides out of the sole, and the input position when vertically kicking the ground is likely to shift toward the ball of little toe as the heel supinates due to the shift of the lower limbs.[0004]With the “lateral bulging” or the heel supination, the central position of the force of kicking the ground during a jump sh...

AI Technical Summary

Benefits of technology

[0006]It is an object of the present invention to improve performances in various sports, e.g., by suppressing the shifting of the input position when vertically kicking the ground toward the ball of little toe or by reducing the loss of time during a direction-changing move or a spiking action, by reducing the amount of “lateral bulging” or suppressing the supination of the heel.

[0016]Thus, the “lateral bulging” or the supination of the heel will be less likely to occur. This will improve the performance of the wearer.

Problems solved by technology

With the “lateral bulging” or the heel supination, the central position of the force of kicking the ground during a jump shifts toward the ball of little toe, and the supinated heel portion needs to be recovered, which may cause a loss of time during a direction-changing move or a spiking action.
