The new Pro-Flex XC Torsion foot from Ossur has been developed to comfortably support the active user who enjoys hiking and jogging, as well as level-ground walking. The Pro-Flex XC Torsion combines the Pro-Flex XC features of energy return and smooth roll-over, with valuable shock absorption and rotational capabilities. The sole blade offers an effective full-length toe, and a wider foot blade than traditional feet. The lightweight anatomical foot cover features a steady-grip sole for barefoot stability on wet or slick surfaces, and a sandal-clamping toe for a range of footwear, including flip flops. Ossur recommends using the Pro-Flex XC Torsion with the Unity sleeveless vacuum-suspension system. This adds minimal weight, no extra build height, and does not interfere with the foot’s dynamics.
