How do the Katapult Shoes work?
In a normal standing position with conventional athletic shoes roughly 2/3rds of the body’s weight is supported or rests on the heels with little effort from the calf muscles. Training in the Katapult shoe eliminates the heel and forces the calf muscles to support the full body load. This overload works the calves and Achilles tendons with a force equal to several times the body’s weight upon impact. Used correctly, the Katapult training shoe stretches and overloads these muscles, which in time will lengthen and strengthen.
