A favorite of guides and snow science professionals who need all day comfort in their touring boots every day, the Dynafit Radical Pro Alpine Touring Ski Boots are light, tough, and comfortable for most feet straight out of the box. With a lightweight Grilamid shell and cuff and fiberglass-reinforced Grilamid spoiler, the weight of the Radical Pro W drops to 1270 grams in a 24.5, light enough for hut work and big vert days, but with a confident 110 flex to handle even wider skis and sketchy snow with ease.
