Ironman® replacement insoles are the latest innovation from Spenco® in cushion replacement insoles. Ironman insoles are designed to provide significantly improved shock absorption then the standard insoles that come with most shoes. The main body of the insole is constructed from a yellow, full length contoured layer of polyurethane. The red pads at the ball of the foot and the heel are embedded shock pads that are designed to give extra cushioning to the weight bearing impact points of the foot. The blue support struts around the heel and arch of the foot add stability to the Ironman insole and help to keep the foot properly aligned over the most shock absorbing parts of the insole. Ironman insoles work well in any shoe with a removable insole including athletic shoes, outdoor shoes, hiking boots and even some casual walking shoes.   Show Less
