The TPR gel in these Spenco Performance Gel Insoles is extremely durable and the lower density orange spots under the heel, ball of the boot, and big toe provide extra soft gel cushioning where needed. These gel insoles feel natural and can be used as replacement insoles. A low friction fabric covers the top of the insole and is designed to reduces moisture build-up.
