Boulder Canyon has a handful of classic, devious slab routes on glassy granite. These “moderates” sometimes pitch 5.13 climbers right off their tiny scoops and dishes. Better bring the Instinct S – SCARPA's softest shoe, with Vibram® XS Grip2 to hang on to the subtlest features. But don’t quit at slab – these train hard, pull plastic, send on techy terrain. The Instinct S’s elasticized fit and synthetic microsuede upper stay sensitive for the life of the slipper.
