The Lange XT3 LV GW boots are a fully-built boot designed to get you up to your favorite line with ease while giving plenty of power to ski the way it was meant to be skied. Lange's Active Power V-Lock combines with a Friction Free Hinge to provide increased range of motion and mobility for efficient uphill travel, and Dual Core Construction and a 130 flex offer unmatched response and power for the downhill. A 97mm last fits narrower feet for that race-like feel.
