Black Diamond Quadrant (2014)

The Quadrant defies convention by bringing skiing performance and stiffness reserved for freeride boots to the touring weight range.
Equal parts downhill crusher and lightweight hiking machine, the Black Diamond Quadrant is for those who want stiff, responsive flex and touring flexibility, and aren't willing to sacrifice either. For Winter 2012/13, the boot's new Efficient Fit AT Liner features improved fit and articulating zones for all-day warmth and touring comfort. The Quadrant's lightweight design and 40 degrees of resistance-free touring touring motion take the grind out of the skin track, and its 4-buckle, overlap shell and redesigned plastic liner tongue allows for maximum power transmission when it's time to drop in.
