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 our 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 sticker 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 Fit: When fitting the Instinct VS, bear in mind that the upper is synthetic, so whilst the shoe will break-in and feel more comfortable after a few uses, it will not stretch at all. This gives you a long-lasting performance fit that will never change, so it performs the same from its first day to its last.
