The Echelon is a waterproof hydraulic ankle that absorbs and dampens on impact, self-aligns on rough and sloping surfaces, then remains dorsiflexed at toe-off. These design features help reduce abnormal pressures at the socket interface and other joints, promoting comfort and postural symmetry.

• Submersion to a depth of 1m
• Independent hydraulic control of plantar and dorsi-flexion
• Biomimetic design simulates natural ankle motion
• Toe up for swing through clearance
• Natural toe position for sitting
• E-carbon heel and toe springs
• Glide sock included
