Palau liners are made with 100% highly rated EVA foam. The thermo-moldable foam is closed-cell which maximizes thermal retention. Palau make their liners with a dense cut of the foam that retains its shape after a heat mold or some skiing. That is why they were chosen as the liner supplier for Dynafit, La Sportiva, and other well-known boot brands. Now you can get replacement liners for lightweight backcountry boots with the aftermarket offering from Palau. The Tour Lite Pro liners are relatively thin, lightweight, and have an Achilles flex zone. Perfect replacements for TLT, Spitfire, and other high performance ski mountaineering boots.
