Ossur Cheetah Xcel

Cheetah Xcel is specifically designed for explosive short-distance sprints. It’s curve compresses upon impact, storing energy and absorbing high levels of stress that would otherwise be absorbed by the athlete’s knee, hip and lower back. The carbon blade features a more extreme curve and the dynamic shape allows for the foot to flex and give a powerful energy kick. A long toe provides better ground contact, while the plantar-flexed pylon handles forward progression. The Cheetah Xcel is an estimated one-third as powerful as a native ankle, returning approximately 90-95% of its energy when the athlete is running.
