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.
