This narrower fitting all mountain boot is designed to accommodate aggressive skiing while also providing the tools for backcountry exploration. Take a walk on the wild side with Lange's new, patented Power V Lock 2.0 alpine touring mode. Designed to allow the cuff to rotate significantly when in walk mode, the V Lock does not compromise downhill performance when in ski mode. The powerful 110 flex skis consistently because of Lange's mono injected shell and cuff, and the ThinsulateR liner is warm and lightweight. For the hard charging girl who truly skis all over the mountain, our advice is give the Lange XT 110 LV Ski Boots a try.
