The Spring Loaded Running Shoes (Women's).

These are the running shoes with shock-absorbing springs in the soles that relieve the stress and fatigue of running better than any shoe available. The shoes' patented springs--two in the forefoot and one in the heel--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. TPR inserts in the heel and forefoot minimize weight. Breathable nylon mesh uppers. White with blue trim. Women's. Whole/half sizes 6-11; Regular width. If in between sizes, order the next larger size. (13 oz.)
