Blurring the lines between freeride skiing and alpine touring, the Maestrale RS ski boot made switching from downhill to tour mode super easy with a new ski/walk mechanism. Range of motion is 37 degrees, impressive for a boot with a 120 flex index and a weight of 3 pounds, 7 ounces. Other features include a stouter power strap with a cut-out that makes adjustment a snap, and oversized buckles that are easy to use, even with gloves. Finer points include Scarpa's Axial Alpine tongue design, polyamide construction, which contributes to the stiff flex, Quick Step tech fittings and a stiff Intuition liner. These hard-charging boots are designed for backcountry skiers who like to drive big skis or seek out steep descents, but want no compromises on the up track either.
