The AvalonK2 Foot  is the latest hydraulic foot/ankle system from Endolite. It enhances walking confidence because it hydraulically adjusts to inclines and steps and features multiaxial ankle motion for increased ground compliance. The AvalonK2 self-aligns to secure the knee joint and encourage good posture and joint position, this enhances trans-femoral knee stability to help prevent falls and it reduces unwanted moments on the knee joint of trans-tibial users. The toes dorsi-flex after mid stance and remain elevated during swing phase providing increased ground clearance for safety and efficiency.


  • Range of true motion, not just foot deflection!
  • Hydraulic ankle provides plantar and dorsi-flexion.
  • Ergonomic keel for ease of rollover.
  • Single valve adjuster
  • Sandle toe allows different footwear styles.
  • Multiaxial ankle motion for increased ground compliance.
