Behind every hard climb there's an aggressive pair of climbing shoes that helped with the first ascent, and Scarpa's Instinct has quite the pedigree of F. A. s. It's an aggressively downturned climbing shoe with a narrow toe, moderate asymmetry, and a women-specific heel to provide a precise performance and solid fit. Vibram's Grip 2 rubber enhances the sole's traction on rock and plastic. The upper is a stretchy microfiber with a Bi-Tension rand that maintains the shoe's aggressive downturn overtime.
