Pro-Flex®

More than a foot. It’s a family.

All Pro-Flex feet feature a unique and propietary 3-blade design with a footblade that incorporates a full effective toe lever and a more anatomical split toe. This innovative design helps generate exceptional toe-off energy and a fluid, natural progression from heel strike to toe-off. Unity compatible and now available with Torsion.
