The F1 LT from Scarpa inherits the ascent DNA of the Alien RS: very lightweight (990 grams per shoe), incredible shaft rotation (72 degrees), and a sporty fit (100 millimeter last). With the F1 LT, Scarpa has managed to elevate the downhill performance of a lightweight shoe to the next level. This is made possible by the 3D-Lambda frame – a kind of skeleton on the shell and the cuff – and the Carbon Grilamid LFT material. Both features enhance flex and torsional stiffness while simultaneously reducing shell thickness, achieving greater strength and lower weight. The progressive flex is likely unique in this weight class and ensures precise ski control. The Gaiter Shell construction forgoes a fixed tongue and is instead equipped with waterproof Lite Shield Tech fabric, effectively preventing snow ingress. At the same time, the Boa Fit System over the foot, a single Fast Buckle Closure strap at the leg, and the Velcro Power Strap above provide excellent support and guarantee even pressure distribution – without pressure points. All three can be quickly, individually, and precisely adjusted. The Speed Lock LT ski-walk mechanism allows for the adjustment of three different forward lean positions – efficiently and quickly. This makes switching between ascent and descent a breeze. The Intuition Tour LT liner ensures a precise yet comfortable fit. The liner is thermoformable, meaning it can be customized. Even with extended use, the feet remain warm and free from pressure points. On the underside of the F1 Lite, the Vibram UFO LT sole offers maximum grip and sensitivity on rock while featuring large, self-cleaning grooves. The perfect shoe for demanding uphill and downhill conditions.
