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.

AI Technical Summary

Benefits of technology

"The present invention provides an arch support insole that solves problems of existing insoles by improving wearing feeling, reducing fatigue on walking, and maintaining the arch support part. The insole is made of a single layer through dual injection, which minimizes the thickness of the insole and reduces manufacturing costs. The insole includes an arch support part curvedly projecting upward to support the arch of the wearer's foot and a heel support part coupled to a rear part of the insole body. The insole also includes an anti-slip part to improve grip on the shoe. The invention provides an arch support insole that improves wearing feeling, reduces fatigue on walking, and maintains the arch support part while minimizing the number of manufacturing processes and cost."

Problems solved by technology

In addition, addition of unnecessary processes upon manufacturing increases the number of manufacturing processes and manufacturing cost.

Further, the insole formed of a single material having no resilience to support the pressure periodically receives shock applied from the ground to the heel to give fatigue on walking for a long time.

Furthermore, long-term use of the insole causes deformation of the arch support part to make it impossible to sufficiently support the arch of the wearer's foot.
