ski mode
When the Pivoting Cuff is locked into
ski mode, the edge of the cuff creates
pressure against the boot shell—the basis
for a progressive alpine feel and f lex.
Other alpine touring boots build in extra
clearance between the cuff and boot shell,
creating good walking characteristics but
poor skiing performance.
walk mode
In traditional alpine touring boot designs,
the cuff edge and middle buckles limit the
forward range of motion in walk mode.
Black Diamond's Pivoting Cuff moves
up and out of the way to allow the boot
to flex farther forward than possible in
conventional alpine touring designs.
resistance-free stride
The result is an unrivaled 40º range
of resis t an ce - f re e motion: 20 º
forward for maximum mobility on
steep climbs and switchbacks, and
20º rear ward for long strides on
rolling terrain.
