insole

Abstract

This article is an insole for insertion into athletic shoes. As shown in the reference diagram, this insole lacks the big toe contact area S1, ball of the foot contact area S2, and arch contact area S3 of the insole of the athletic shoe, and has an overall shape that is roughly crescent-shaped. In addition, a part of the outer edge line a on the medial side indents in a roughly arc shape toward the lateral side of the center line CL. Furthermore, it is formed with a slope such that its thickness increases from the medial side toward the lateral side. The insole shown in the drawings of this application is for the right foot, and the insole for the left foot has a shape that is symmetrical to it.
