The Lange XT3 120 Alpine Touring Boot blends the downhill performance of an alpine boot with the uphill performance of a touring boot. The downhill performance is made possible by the powerful 120 flex that drives power to our edges and the timeless 2-piece, 4-buckle design. Meanwhile, the 53° range of motion provided by the walk mode ensures we can scamper up skin tracks with ease. Finally, the thermomoldable liner keeps our feet warm and comfortable through it all.
