The ALPS Smart Seal Liner features raised bands that grip the socket wall to form a secure interface. The low modulus bands stretch against the socket wall, while the smooth inner wall conforms easily to the residual limb. The Smart Seal Liner has a new seamless knitted construction with a modern look and is available in locking and cushion suspension. The locking version features a new distal construction to control distal distraction.

Transtibial (SB) rings begin 2.9 inches from the center of the distal end.
