shoe insoles

Abstract

This product is a shoe insole primarily intended for use in athletic shoes. As shown in the "bottom view," it has a cross-shaped recess on the bottom side, and as shown in each end view, the thickness gradually decreases in the front, back, left, and right directions from the intersection of the recesses, facilitating load transfer (weight transfer). Furthermore, as shown in the "plan view," by reducing the amount of flexion towards the big toe on the toe side, the gap between the shoe insole and the little toe side of this product is eliminated, as shown in each reference usage diagram, making it easier to apply force with the little toe.
