Scarpa F1 GT ski boot is the essential and comfortable boot. As the stripped-down version of the F1, the SCARPA Women's F1 GT ski boot is light enough to take on multi-day expeditions while still offering the performance you want when skiing off big peaks. A Grilamid cuff offers all the benefits of Polyamide, including reliable performance across a large temperature range and progressive flex. Combine the shell with a two-buckle closure and a single-finger strap and you get a 90-flex boot that is capable of driving your skis, even when mountain conditions are sub-optimal. With a 72-degree range of motion in walk mode, the F1 GT lets you make the most of every stride, saving you precious time and energy on the climb. And in case you can't skin straight to the summit, there is also a Vibram sole, so you never have to second guess your footing as you boot to the top.
