The Lange XT3 Free 115 W MV redefines what a modern freeride touring boot can be. Designed for women who demand effortless mobility on the climb and uncompromising power on the descent, it blends touring efficiency with true alpine authority.
At the heart of the XT3 is Lange’s Active Power V-Lock, delivering a dramatically increased range of motion in hike mode for long, efficient skin tracks and boot packs. Switch to ski mode and the boot locks down with the confidence and precision of a dedicated alpine boot — no compromise, no hesitation.
The lightweight Dual Core Light shell construction actively stores and releases energy as you flex, producing powerful rebound, smooth flex, and exceptional snow feel. Combined with a women-specific cuff and shell, the result is a boot that feels intuitive, reactive, and perfectly balanced.
From friction-free mobility to Dynafit®-certified tech inserts and GripWalk® soles, every detail of the XT3 Free 115 W MV is purpose-built for freeriders who earn their turns — and ski them hard.

Ski boots are sized in Mondopoint, based on the length of your foot in centimeters. The chart below is a general reference for converting between sizing systems.
This chart is not a fitting. The only way to know your ski boot size is to be fit in person, either with a Boot Fitting at our shop or from a professional fitting you have had elsewhere. Sizing, shape, and volume vary by brand and model, and a performance fit is snugger than your street shoe. Unworn boots can be returned under our return policy, but a boot that doesn't fit can be a big hassle for your trip if you haven't tried it on.

Conversions are approximate and can differ by half a size between brands.
Ski boots are built with one shell for each full and half size, so a 27 and a 27.5 are the same boot with a different liner or footboard. That is why sizes are listed together, like 27/27.5.
Very few models differ from this. Scarpa is the main exception, pairing sizes the other way (for example, 26.5/27 share a shell). When a model is sized differently, we call it out on that product's page.
