Designed for ladies who like to ski all over the mountain, the Nordica Firearrow F3 Women's Ski Boot is built to drive today's wider skis with unparalleled precision. Checking in with a progressive flex of 105, the F3 features a three-piece PU ether shell that makes it easy to get on and off, while offering superior lateral energy transmission to help you master your new fat boards. To better transfer power to your edges, Nordica built the F3's EDT boot board out of carbon fiber, which increases the torsional rigidity of the boot, reducing energy loss and increasing precision. Additionally, the shell and tongue rate high on Nordica's rebound scale, meaning they push back quickly when flexed, giving you energy to quickly transition into your next turn. If you encounter varying conditions on the slopes, or feel like charging hard in the morning and cruising in the afternoon, there's a simple allen-wrench adjustment system on the spine of the boot that allows you to fine-tune the flex to suit your situation. To avoid the classic heel-hold problems of 4-buckle boots, Nordica has equipped the F3 with 3 buckles, one of which is aligned at a 45-degree angle to the ankle joint to pull your heel directly back into the heel pocket, increasing hold, performance, and comfort. The PFP precision liner is designed specifically for women and features heat-moldable technology to dial in the fit, and micro-adjustable buckles allow you to further adjust over the course of the day.
