The high-end ski touring and freetouring boots Lange XT3 Tour Pro Power Blue (ref. LBK7310) are Lange's benchmark for maximum performance and stiffness for expert skiers. They are the equivalent of a lightweight competition supercar with a carbon-fiber monocoque and track-tuned suspension: built in Grilamid with a powerful 130 flex for wild, instant power transmission on the descent, combined with 53° of cuff range of motion and weighing just 1,520 grams to devour vertical gain without fatigue. They feature the metal-on-metal Active Power V-Lock 3.0 locking mechanism, Dual Core Light Grilamid shell, precise 99 mm last, Vibram® ISO 9523 touring sole, Dynafit Certified Tech Inserts, and heat-moldable Touring Liner Custom Pro.
