Combining ultralight elements of the Scarpa Alien race boots with a more versatile, backcountry-oriented design, the all-new Scarpa F1 LT is their lightest weight alpine touring boot, optimized for high-mileage missions, ambitious traverses, and technical ski mountaineering descents. 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.
