The Scarpa Maestrale RS ski boots are for experienced backcountry skiers who want uncompromised performance. This is one of the best-selling backcountry boots of all time, so there is a reason why you see so many of them on the skin track, at the resort prior to opening chair or deep in the backcountry. With a stout 125 flex, you have plenty of power to drive the widest and stiffest skis for the descent. With a 102 last, this Maestrale is best suited for skiers with average to slightly wide feet. A stiff Grilamid and Carbon frame delivers laser-like precision on precarious terrain and integrates power efficiently from the driver to the boot to the binding to the ski. A large Velcro power strap increases effective vertical height for extra leverage. One large buckle connected to a wire harness evenly wraps the shell around your foot for an even and secure fit. The Scarpa Maestrale is a time tested, boot business game-changer serving up fast and light charging for "earn your turns" skiers.
