Combining a curved, asymmetrical last with a soft construction and thin sole for enhanced flexibility and sensitivity, the Instinct VS Women's is the cornerstone of Scarpa's Performance line—an all-around shoe that handles a variety of styles at the highest level. The Instinct VS Women's features a modified heel cup to better suit lower volume feet and also utilizes softer and stickier XS Grip 2 rubber. Bi-Tension™ active rand provides maximum toe power Vibram® XS Grip 2 for a softer, more supple fit and feel Floating power strap enhances fit and provides power Rubber toe patch provides maximum toe hooking power Perfect for bouldering, sport climbing, and technical face climbing Features BI-TENSION SYSTEM Bi-Tension system is a tensioned rubber wrap reaching down two sides of the shoe. It gives priority to sensitivity and subtle support. Specially adapted to the slightly asymmetrical models, Bi-Tension runs under the front of the toes and draws down along the sides of the foot, leaving the center pad for sensitivity. RUBBER TOE PATCH Rubber toe patch provides maximum toe hooking power.
