The Scarpa Instinct VSR Climbing Shoe is a high end bouldering and sport climbing shoe. The shoe is downturned and aggressively shaped with a single Velcro strap securing system across the top. The VSR has a large elastic cuff section, with a tab that makes it easy to pull over your foot. The design is similar to that of a slipper and feels really comfortable when wearing them. The Scarpa Instinct VSR has the same shape as the original Scarpa VS but features the softer, sticker Vibram SX Grip 2 rubber. The softness of the rubber is useful for over boulder routes when sensitivity is key. Scarpa Instinct VSR Climbing Shoe | Tech Spec Review
