Salomon’s Ride & Hike Technology features a magnesium backbone that creates a supportive spine for skiing and a wide cuff opening when hiking—at the flip of a lever. The lightweight shell combines new Twin Frame and 360 Degree Custom Shell technologies, melding a rigid upper shell with a fully-moldable lower shell for power and performance and a customized, pressure point-free fit. Additional comfort features include a roomier toe box and rearward foot positioning for better heel hold. Note: this boot's last size can range from 98 to 104 mm.
