F1 LT M Ski Boots 2026

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.
