2 Product description

The 17CF1 Carbon Ankle Seven is designed to initiate extension moments of the hip and knee
during walking and thus achieve extension and knee stability in the lower limbs. The energy gen­
erated during heel strike is stored in the carbon matrix and returned at toe-off. In contrast to con­
ventional ankle joint orthoses, the limits in the plantar and dorsal direction are dynamic and are
not subject to static restriction. Due to its design, the carbon spring has a natural outward foot
rotation of 7°.
