F1 LT

Some boots simply do the job, and some boots disappear under your foot until you forget you're wearing them. The Scarpa F1 LT belongs to the second category: it's the lightest model in the Italian brand's entire Alpine Touring range, born from the same lineage as the Alien race boots but built for those who chain together long vertical days, ambitious traverses and technical descents without wanting to carry a single extra gram. The Carbon Grilamid LFT shell, reinforced with long carbon fibers and built on the 3D Lambda Frame structure, achieves that rare balance between torsional stiffness and contained weight, so the energy invested in every uphill stride transfers without loss to the ski on the way down.

The Speed Lock LT ski/walk mechanism sums up the model's philosophy well: a single motion to switch from climb mode to ski mode, with three forward lean positions (9°-11°-13°) extendable by another 2° thanks to the Spoiler LT when it's time to push through the descent. The closure pairs the BOA® Fit System, capable of millimeter-precise adjustments with a simple turn of the dial, with a Fast Buckle lever and a removable Velcro strap that spreads pressure without hot spots. Inside, the Tour LT thermal liner in Intuition foam molds to the foot after heat-molding and adds agility on the skin track thanks to its flex inserts, while the integrated RECCO® system adds that quiet layer of security every experienced ski mountaineer knows to appreciate when conditions turn.

TECHNICAL INFORMATION

• Carbon Grilamid LFT® - high-performance polyamide reinforced with long carbon fibers that increases stiffness and resistance without adding weight.
• 3D Lambda Frame - shell structure that improves lateral stability and uniform torsional rigidity from heel to toe.
• Speed Lock LT - ski/walk mechanism that allows the forward lean angle to be adjusted across 3 positions and switches quickly between climb and descent mode.
• Spoiler LT - accessory that adds an extra 2° of forward lean to improve impulse transmission on the descent.
• BOA® Fit System - micro-adjustable dial closure system that delivers a precise, consistent fit throughout the activity.
• Tour LT (Intuition Foam) - thermoformable inner liner with flex inserts that improve agility and walkability.
• Zeppa LT - wedge placed between the shell and liner that increases internal volume and improves comfort.
• RECCO® - integrated reflector that allows rescue teams to locate the person in the event of an avalanche.
• Quick Step-In - inserts that make it fast and secure to click the boot into the binding.
