Opened but unused. M size: 24-26cm Five-finger socks that firmly grip the ground at all times, generating kicking power. These five-finger socks firmly grip the ground, allowing you to step down firmly without power loss. The contact surface from the heel to the ball of the big toe is woven with fibers that have frictional resistance, improving grip with the shoes, allowing you to kick off firmly. Arch support alleviates the impact on the arch of the foot (inner longitudinal arch), maintaining the spring function of the foot. The integration with taping-like support that prevents ankle wobble increases the holding power, making it easier to stabilize. A three-dimensional reinforced structure that is difficult to damage is used on the toes, improving durability. ● Materials: Nylon, cotton, polyester, acrylic, polyurethane ● Color: BLU Blue ● Made in Japan
