The Lady's Spring Loaded Racing Shoes

These are the racing shoes with shock-absorbing springs that relieve the stress and fatigue of running so effectively that USA Track & Field has deemed their use illegal for providing athletes an unfair advantage. With two in the forefoot and one in the heel, the shoes' patented stainless steel springs return up to 96% of the energy from each stride that would otherwise be lost to the ground. The downward force deflected and dispersed during each impact is recycled to the wearer as propulsive energy, further reducing the strain on the feet and reducing overall recovery time. Unlike the gels used for cushioning on other athletic shoes, these springs will never break down or degrade. The shoes have injection-molded EVA foam midsoles that work in conjunction with the springs for maximum cushioning and resiliency; with removable EVA sock liner to allow for orthotic use. A fiberglass-reinforced nylon shank provides midfoot stability. Breathable nylon mesh uppers. Black with Pink trim. Regular width. If in-between sizes, order the next larger size. (8 1/2 oz.)
