Bi-Tension Rand | Using a reverse slingshot design, this system connects your heel to your toe, resulting in less foot discomfort and more power being driven towards your primary edging surface.
Vibram Rubber | Stiff enough to let you stand on the thinnest edges, the XS Edge rubber in the forefoot pairs perfectly with the stickier XS Grip 2 heel rubber that molds perfectly to heel hooks on any rock type.
Flexan Dynamic Midsole | Offsetting the softer upper, the redesigned Flexan midsole is slightly stiffer, offering plenty of support and reducing foot fatigue on multi-pitch routes.
Firm and Reinforcing | A bit more flexible than the Instinct, the Instinct VS features a slimmer sole for enhanced sensitivity, allowing you to sense the terrain below your feet.
Toe Rubber | A large patch of rubber on top gives you maximum coverage for toe hooks and bat hangs.
