The Iceross Synergy liner incorporates a unique combination of two different silicone durometers to provide balance of comfort and stability.

A firm silicone outer layer provides outstanding stability for active
use, while a softer shock-absorbing inner layer nurtures the skin,
offering superb suspension and comfort.

Össur recommends that Iceross Synergy Liner is used in conjunction
with the Icelock® 600 Series.
