The cool Storm Blue of Lange s third generation XT looms large over the crossover boot landscape, bringing big improvements to both the uphill travel and downhill performance. Active Power V-Lock 3.0 and Friction-Free Hinges work together to create incredible ROM efficiency for a smooth and easy stride on the uphill jaunt. The new Dual Core Light shells are now made from PU instead of Grilamid for a super reactive, shock-absorbing, and less temp-sensitive ride while keeping the weight in the realm of the reasonable. A new Performance Bootboard provides incredible snow-feel and warmth. A burlier, warmer and more precise Dual 3D Full liner with Ultralon® foam is a dream to ski in. We could go on and on, but if you want a boot that can handle it all, it doesn't get any better than the new Lange XT3 130 LV Alpine Touring Ski Boots.
