  • Patent number: 5511324
    Abstract: An athletic shoe device that fits through the wedge sole and insole through a hole in the heel area of a sports shoe, which I named the Roosevelt Spring. The spring is activated with the weight of an athlete, while walking or running, this is done by absorbing the shock and giving energy in sequence to the athlete without losing balance or stability, and causes no pain in the foot. The athlete is also supported by the strength of the spring. It increases the lifetime to the sport shoes and will help be responsible for the decline in sports related injuries, as well as enable man to go farther and faster.
