The Instinct VS, subtlety blends the characteristics of the Slipper and Lace-Up versions to create a superb technical shoe. The Instinct VS features the same Micro-Suede upper used on the Instinct Slipper which provides great flexibility and ensures that the shoes hold their shape longer than leather equivalents The upper is built around the down-turned toe last of the Instinct family ensuring precise toe placements with high levels of feedback. Vibram XS-Edge ensures that your feet will stay planted on the smallest of edges and stiffens up the toe increasing responsiveness. Bi-Tension technology intimately connects the toe and the heel of the boot helping to increase overall performance which is guaranteed to last. Velcro straps keep the heel of the shoe firmly secured to your foot even on the most demanding heel-hooks with the new toe rand design providing durable performance on toe-hooks.Scarpa Instinct VS 40/45 Features: Last FV Sole Vibram XS Edge 3.5 mm Upper Synthetic Micro Suede+ Suede Weight 230g
