Combining ultralight elements of our Alien race boots with a more versatile, backcountry-oriented design, the all-new F1 LT WOMAN'S is our lightest weight, womens-specific alpine touring boot, optimized for high-mileage missions, ambitious traverses, and technical ski mountaineering descents. The Carbon Grilamid® shell and gender specific cuff provide a strong yet superlight construction, with a massive 72 degree cuff range of motion that increases agility and reduces fatigue. The Intuition liner is tailored for women, setting the standard for thermo-formable fit, warmth and comfort. The category-defying F1 LT W's redefines what's possible in the backcountry. Carbon Grilamid® LFT shell and cuff are made of CG-LFT, a carbon-reinforced polymer that is super-light but still stiff and strong. Speed Lock LT: Simple and secure, with 3 forward lean positions, the Speed Lock LT ski-walk mechanism is strong and reliable on the downhill and fast on the transitions. Fast Buckle Closure: One buckle and a wide hook and loop strap that guarantees a rapid and precise closure. Flip the FBC open and Speed Lock LT up and you are ready to tour. BOA® Fit Sytem: Dial in the perfect fit with out exclusive floating BOA®Fit System closure, providing precise and secure adjustments with no pressure points. Vibram® UFO RS Sole: made with TOP85 compound that offers great durability and grip in cold conditions. 3D Lamda Frame: Similar to an i-beam, the 3D Lambda Frame adds raised ribs of Carbon Grilamid® LFT in a specific pattern along both sides of the shell. This design significantly increases strength, durability and torsional rigidity with minimal added weight. The 3D Lambda Frame improves responsiveness and overall performance, allowing you to focus on the terrain, and not your boots. Cuff : Carbon Grilamid® LFT. Ski/Walk Mode : Speed Lock LT.
