The Scarpa Men's R-Evolution GTX Backpacking Boot performs well enough for speed/fitness hiking, but has no problem doing a car-to-car ascent of longs peak. A Gore-Tex membrane sweetens the deal even more by delivering waterproof, breathable performance, and the Revolution EVA midsole helps cradle your feet over miles of rock-strewn moraines. It will carry you over miles of rugged terrain with minimal weight and plenty of support. Blending the comfort of a lightweight hiker with the support of an alpine boot, Scarpa's Sock-Fit DV construction uses both Schoeller stretch material and memory foam to deliver a snug and comfortable fit that still delivers support for hiking with a heavy pack. In addition to being durable, the suede upper will tighten progressively for a sweet blend of comfort and traction.
