The Lady's Spring-Loaded Running Shoes

These are the lady’s running shoes with shock-absorbing springs that relieve the stress and fatigue of running. 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; removable EVA footbed enables orthotic use. A rigid TPU shank provides midfoot support and stability. Breathable nylon mesh uppers. Black or White. Medium width. Half sizes 8 1/2. (9 3/4 oz.)
