The Scarpa Maestrale RS strikes the perfect balance between uphill efficiency and downhill authority, making it the go-to choice for serious backcountry skiers who refuse to compromise on either front. Built with innovative Grilamid BIO and Carbon Core construction, this alpine touring boot delivers responsive power transmission without the weight penalty, while the impressive 61-degree range of motion ensures your stride stays smooth and efficient on endless skin tracks. The anatomically reshaped 102mm last paired with a moldable Pro Flex Performance liner creates a precision fit that keeps you comfortable through dawn-to-dusk tours, while the progressive Pebax flex system adapts seamlessly from climbing mode to full ski performance when it's time to drop in and make those hard-earned turns count.
