Freedom Kinterra 2.0

FREEDOM Kinterra is a hydraulic ankle combined with a carbon fiber foot which lets moderately active to highly active users walk with a natural gait on all types of surface and at all speeds. 

The Kinterra articulated ankle-foot system offers:
Better ground contact and a more symmetrical gait
Improved stability and safety, especially on slopes and uneven ground
Reduced socket pressure for healthier stumps
• Enhanced comfort when sitting, standing or crouching
• The ability to touch the ground and squat with greater stability and comfort

12° of ankle flexion

The ankle joint mechanism provides 10° of plantar flexion and 2° of dorsiflexion for better ground contact.

Stumble prevention

A dorsi-assist spring lifts the toe during the swing phase to make it easier for the user to negotiate sudden changes in slope gradient and thus prevent stumbles.
