The Prime is Black Diamond's premier 3 buckle lightweight alpine touring boot-designed to tackle technical ski mountaineering routes, or long distance apporaches. This is BD's lightest alpine touring boot, featuring a unique 3-buckle design that skis with the stiffness and control of a 4-buckle boot. Its state-of-the-art construction keeps weight to an absolute minimum, while our revolutionary Pivoting Cuff Technology delivers the ultimate combination of freedom of motion in walk mode and instant power transfer in ski mode. This year, the Prime features a redesigned liner for all-day touring comfort in any weather.


  • Triax Pivot Frame with Flex 110, 40º of resistance-free touring motion and locking QuickWire cuff buckles
  • New 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 dynamic grip and durability
  • 103 mm V-shaped last with performance, out-of-box fit; 100% thermoformable
