Single-layered arch support insole to be inserted into shoe

Abstract

Provided is an arch support insole to be inserted into a shoe. The insole should satisfy tasks for a wearer as follows: (1) improvement of wearing feeling by maximally reducing the thickness of the insole, (2) reduction of fatigue on walking by maximally preventing transmission of shocks, and (3) sufficient support of the arch of the wearer by maintaining an original shape of the arch support part. In addition, these tasks should be solved by a minimum number of manufacturing processes and minimum cost. The arch support insole includes an insole main body having a portion or the entire of an arch support part curvedly projecting upward to support the arch of a wearer's foot, and a heel support part coupled to a rear part of the insole main body, wherein the insole main body and the heel support part are formed of a single layer by dual injection, the insole main body is formed of a material having hardness higher than that of the heel support part, and a plurality of honeycomb-shaped projections are formed downward at a bottom surface of the curved arch support part.
