Rolling us through easy steps on harsh terrain is the Scarpa Ribelle HD Mountaineering Boot. The platform's Dynamic Tech Roll System delivers a rockered forefoot that boosts our walking efficiency by smoothing out our transitions between steps, and the midsole's dual-density PU compound absorbs shock and returns energy throughout every mile and despite chilly temps. Snow, slush, rain--nothing is getting by the HDry membrane, and when things get icy, the rear heel welt accommodates our semi-auto crampons. Color: blue
