Scarpa's trekking and backpacking boots draw heavily on the prowess of their technical boots. The R-evolution adopts Sock-Fit XT and memory foam for impeccable comfort but also the control and precision necessary for crossing exposed, rough terrain. Scarpa collaborated with Vibram to create the Fagus Lite sole, which features a trek-specific pattern, adapted to a variety of surfaces. The midsole is molded EVA, to keep feet happy in wet conditions but there's also a Gore-Tex liner for waterproof comfort. * Main product photo is Tundra.
