Scarpa made the Men's Booster S Climbing Shoe for anything overhung at the local gym, sport crag, or boulder field. It has the same aggressive downturn and sharp asymmetry as Scarpa's Boostic Climbing Shoe, except Vibram's XS Grip rubber gives this shoe as softer feel for more sensitivity and friction. It features a unique Tri-Tension randing system that prolongs the shoe's downturn and pushes all the power directly to the toe for a technical performance. Expect the microsuede upper to stretch a half size to full size for a customized feel.
