SPRINTER’S KING

SPRINTER’S KING IS A RUNNING FOOT, SPORT DEVICE AND NOT MEDICAL DEVICE.

The Innovative morphology  allows the optimization of ankle plantarflexion. The position of the bracket allows to optimize release of foot’s elastic energy.   The width’s foot is similar to the sound limb foot. The Sprinter’s King eliminates the negative force component opposite to the forward direction that has the other running feet on the market.

It allows the maximum elastic response and optains the best efficiency as 85%.

Material: carbon fiber. Warranty: 12 months
