Kinterra™ Foot/Ankle System

Extraordinarily Normal.

The Kinterra™ Foot/Ankle System combines hydraulics and carbon fiber technology to provide low to moderate impact K3 ambulators an exceptionally normal walking gait — regardless of surface angle or speed. The result is rock solid stability and the confidence for users to choose a new path.

Kinterra’s articulating ankle delivers

  • Increased ground contact and a more symmetrical gait
  • Improved stability and safety, especially on slopes and varied terrain
  • Reduced socket pressures for healthier residual limbs
  • Enhanced comfort while sitting and squatting
