These are the walking shoes with patented spring-cushioning in the soles that help relieve back pain. The downward force of each step is deflected, dispersed, and recycled to the wearer as propulsive energy, reducing the strain and stress on one’s muscles and joints. Unlike the compressed foams and gels used for cushioning on other athletic shoes, the springs will never break down or degrade. The shoes have a full-grain leather upper, mesh tongue, removable memory foam foot-bed, and slip-resistant rubber outsole. Each shoe contains one stainless steel spring in the heel and two in the forefoot. White/Navy or Black. Men’s whole sizes 9-13.
