Combining ultralight elements of our Alien race boots with a more versatile, backcountry-oriented design, the all-new F1 LT is our lightest-weight alpine touring boot, optimized for high-mileage missions, ambitious traverses, and technical ski mountaineering descents.
- 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 SytemL Dial in the perfect fit without 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
BOA FIT SYSTEM
- The patented Boa Fit System consists of three integral parts: a micro-adjustable dial, super-strong lightweight laces, and low-friction lace guides. Each unique configuration is engineered for effortless precision delivering a connected, fast, customized, and durable fit, and is backed by The Boa Guarantee. The F1 LT system is an exclusive floating system located under the waterproof fabric cover that contracts downwards on the instep of the liner as the dial is tightened, precisely controlling volume and fit.
3D LAMBDA 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.
