Charge down, shift, climb up. Designed for women who love to cruise through unspoiled powder at high speed, but are tempted by the occasional escapade to hike a new peak, Salomon's SHIFT PRO 90 combines the stability and power of a true alpine boot with the versatility of a touring boot fit for the whole mountain. Inbounds or out of bounds, the shift has never been easier! S/PRO’s 100 mm inclusive fit and CustomFit 4D liner with thermoformable Talyn combined with a softer Sensifit insert provide better instant fit and more comfort when touring. The Coreframe insert delivers improved terrain feedback and power transmission for a unique downhill performance. At 1.6 kg, this boot makes it easy to hike up. The Surelock skiwalk mechanism increases cuff mobility, while the integrated tech inserts ensure direct power transmission.
