SCARPA Instinct S is a versatile and high-performance climbing shoe designed primarily for bouldering and training in the gym, but which allows you to perform well even on the crag.The upper is made of microfiber, with an elastic closure with REB Reinforced Elastic Band technology that makes it long-lasting. In the area above the fingers there is a large rubber cover that allows you incredible toe hooks. The heel area is slightly asymmetrical and pointing downwards with a medium angled toe that allows you to feel sensitive and precise.The rubber used for these inserts is the M50, soft and with exceptional grip, which combines perfectly with the 3.5 mm Vibram XS Grip 2 used for the sole.
