【Foot-shaped grip】 These foot-shaped non-slip socks were developed based on the shape of the sole for use by the Japan Self-Defense Force during martial arts training. They provide sturdy grip from your heels to your toes.
The two additional red anti-slip patches on the balls of the feet provide further increased grip.
