The Scarpa Instinct SR is a slipper with a wide heel and good friction properties thanks to the Vibram XS Grip 2 sole. It was specially developed for indoor climbing. The slipper has a slightly asymmetrical and pre-tensioned shape with M50 rubber over the toe box and on the heel for optimal hooking. Due to the bi-tension construction, it is very precise and remains dimensionally stable. The ergonomic shape adapts perfectly to the foot and sits like a second skin.
