The Formula posterior mount (PM) foot is the ideal balance of flexibility and power, creating a dynamic foot design intended for a wide range of users/patients.
The long, lightweight carbon pylon provides critical energy return to the user through the posterior attachment, while the compact shape of the ankle allows for better cosmetic finishing without hindering foot performance while worn with a shoe.
Everyday users to elite athletes will admire the active feel of the Formula, and practitioners will appreciate the diverse range of fitting options for their patients.
