The ALPS Extreme locking liner is the perfect fit for transfemoral and active transtibial amputees. The Extreme offers 80% less vertical stretch than our other gel liners, which allows users to experience more control and stability during increased activity. This liner is formulated with ALPS Grip Gel or High Density Gel, which both contain properties that help facilitate the donning process as well as reduce pistoning and bunching behind the knee.
