When we are headed deep into the backcountry to ski an exposed line, we trust the downhill performance and uphill prowess of the Lange XT3 TOUR Pro Alpine Touring Boot. The 4-buckle design, 99mm last, and versatile 115 flex provides the power transfer and control we expect from Lange. On the uphill, the full touring norm design, Vibram sole, and lightweight shell ensure we can get to the top of our line with energy left to ski it.
