Insole

Abstract

An insole including a main body having a bottom face and a top face with a configuration adapted to a curvature of a human sole. The top face has a heel section, a hollow section and a toe section. The heel section has a substantially concaved structure with a higher periphery and a lower central portion. The hollow section integrally forward extends from the heel section and has a substantially convex structure adapted to the configuration of human sole. The hollow section gradually ascends in accordance with an inner side of the human sole, whereby the insole can snugly and tenderly attach to the heel and hollow of the human sole. The bottom face is a plane face. Two sides of the bottom face upward extend to increase the contact area with the ground and enhance firmness and flexibility of the insole.
