The Scarpa Women's R-Evolution Plus GTX adopts the Sock-Fit XT and memory foam for impeccable comfort, but more important, control and precision necessary for crossing exposed, rough terrain. They collaborated with Vibram to create the Fagus Lite sole, which features a trek-specific pattern, adapted to a variety of surfaces. The ridgeline standing between you and your campsite consists of loose scree, trail-less terrain, and chances of rain. This burly boot boasts a durable upper made with nubuck leather and a waterproof, breathable Gore-Tex Performance Comfort membrane to handle any terrain in any condition. Underfoot, the R-Evolution features an Active Plus footbed and high-density EVA midsole to keep a spring in your step during high-mileage days. Vibram's Driade rubber comes in a trek-specific tread to adapt to the variety of surfaces you'll encounter in the mountains.
