Shoe insoles

Abstract

The shoe insole of the article according to the present design is integrally formed by joining a hard material (hard plastic) and a soft material (elastomer) by the double injection method. The article has a soft material (elastomer) attached to the back of the heel, which has excellent shock absorption properties and can reduce shock to the body. In addition, the article has a gap formed in the hard material (hard plastic) on the outer part of the heel, which can reduce the impact when landing. In addition, the article has an arch formed in the metatarsal part, which can prevent the foot from widening, reducing the burden on wide feet and bunions.
