The Lange XT 130 LV Ski Boots are the first no compromise high performance boots that climb. Natural Stance, mono injected shells and Control Fit are combined with ultra durable grip soles and arches, lightweight components, and Power V Lock shell technology. The unique new, patented Power V Lock provides excellent climbing range of motion. But, unlike all other AT and sidecountry boots, XT's feature a structurally superior, performance lower shell. The Power V Lock integrates into the lower shell for powerful downhill high performance skiing. Want a walk mode without giving up downhill performance Now's your chance.
