Black Diamond - Quadrant AT Ski Boot (Fall 2014)

Availability: Out of stock

Stock #: 312U-

Black Diamond's premier 4-buckle freetouring boot, the Quadrant defies convention by bringing skiing performance and stiffness previously reserved for freeride boots to the touring weight range. Designed with technical mountains like La Grave in mind, where long climbs lead to no-fall-zone skiing, this boot matches touring comfort and minimal weight with the power and performance to drive big, 95 mm-plus waist skis in high-consequence terrain. Thanks to its patent-pending Pivoting Cuff Technology, the Quadrant has introduced a level of performance that's never before been possible in a lightweight boot. This year, the liner has been redesigned for cold-weather performance.


  • Triax Pivot frame with Flex 120, 40° of resistance-free touring motion and locking QuickWire buckles
  • Plastic liner tongue for a smooth, evenly distributed flex and a wide power strap
  • AT liner with reflective metalized Strobel base, articulated flex zones and taped seams for all-day cold-weather touring comfort
  • Rockered, rubber outsole with integrated tech inserts provides dramatic grip and durability
  • 103 mm V-shaped last with performance, out-of-box fit; 100% thermoformable
