The Scarpa F1 women's ski boots are as comfortable uphill as they are downhill. If you feel that some ski boots sacrifice uphill performance for downhill or vice versa, you will particularly appreciate the versatility of the Scarpa F1. The use of Carbon Core Technology allows the Scarpa F1 to offer increased lateral support and rigidity. Additionally, the inclusion of Axial Alpine Technology ensures better shin support, allowing you to gain precision. The rear lever system, walk/ski, is designed for simple and quick use. To best fit your foot, the Scarpa F1 features the Boa® closure system. This allows you to precisely tighten the boot for optimal support and comfort. Finally, two straps (one with a Recco® reflector) allow you to complete the tightening for exceptional shin support to maximize your footing.
