http://www.hoopskills.com/jumping/strengthshoes.html — Strength Systems, Inc. created the concept of frontal platform shoes. In regular shoes, 70% of the body's weight rests on the heel. Therefore, the calf muscles exert little effort in supporting the body. In Strength Shoes, the heel is eliminated, causing the calves to support 100% of the body's weight. This overload works the calves and Achilles tendons with a force equal to 6 times the body's weight upon impact. Jump higher.
