Lange drops into true touring boot territory with the introduction of the XT3 Tour series. The Lange XT3 Tour Sport Alpine Touring Ski Boots are the middle of the range flex-wise, with a flex index of 120 and a weight of 1525 grams in a 26.5 size. Still a bomber overlap design with four buckles, the XT3 Tour Sport "makes weight" by going to a Grilamid® shell with glued on Vibram® Touring Sole. Using the excellent Friction Free Hinge from the XT3, Lange's new Tour group competes on an even weight footing with many established touring boots, and may well out-ski them.

Product Details


Last: 99mm – A "narrow average" fit designed to fit most skiers, especially if you have access to professional bootfitting.

EVA Lightweight Touring Liner – Lange drops bulk and weight in the XT3 Tour liners but retains the comfort with heat moldable closed cell EVA foam.

Shell Materials

Cuff – Lyftran™ PP

Shell – Grilamid®

Dual Core Light – A lightweight version of Lange's innovative Dual Core technology. As you drive and flex into your boots, Dual Core Light actively compresses and expands – harnessing potential energy to deliver explosive power, snap, and rebound. Imagine lightweight precision and response, easy entry-and-exit, and a new level of ski boot performance as reactive and dynamic as your own body.

Ski/Walk Mode

Active Power V-Lock 3.0 – The heart of Lange's all-new XT3, Active Power V-Lock is Lange's patented new multi-performance freetouring technology. Designed to get you up with ease, but powered for the down, Active Power V-Lock delivers an 11° increase in forward ROM in Hike mode, making long skin strides and hikes more efficient and less fatiguing. But lock it down for the descent with a Ski mode that offers the rock-solid connection of a traditional ski boot and you'll instantly feel the power, precision, and control you've been looking for when it's all about the down.

Friction-Free Hinge – Lange's Friction-Free Hinge delivers a critical free-touring solution: ROM efficiency. More efficient range-of-motion (ROM) provides the freedom for fluid, natural movements on the ascent, providing more flow for a more effortless, less fatiguing skinning and hiking stride.
