The Scarpa Maestrale RS Alpine Touring Boot pairs a Grilamid shell with a Pebax Rnew cuff to deliver a genuine 130 flex, the kind of stiffness usually reserved for resort-only boots. A redesigned four-buckle closure with the Booster Active Power Strap wraps the foot in a uniform, high-tension hold that shuts down heel lift and keeps power moving straight to the edge. Speed Lock 4 still opens to a 19-degree forward lean across four walk-mode positions, so that power doesn't come at the cost of a natural stride on the way up. What Our Gearhead(R) Experts Are Saying:"I climbed for hours expecting to pay for that flex on the way up, but the Maestrale RS still drove hard turns on the descent exactly like a boot built only for the resort."
