Our flagship boot dials up the stiffness for serious all mountain performance. Constructed around an asymmetrical upper that conforms perfectly to your foot and calf, the Index is brimming with future tech including a top-of-the-line BOA Fit System and our unique Internal Heel Lock. The revolutionary wraparound liner delivers next-level comfort and a heat-moldable fit, while seamless construction, an ArmorTech toe and upgraded Storm Cover provide shelter from the harshest elements.

• The Index features our exclusive Diamond Level liner. Made from state-of-the-art memory foam, it delivers a secure, custom fit with more consistent forward flex.
• A Vibram Approach outsole offers best-in-class grip on hard snow and ice - perfect for scrambling on ridgelines, hiking the pipe or just navigating a sketchy parking lot.
• The Index is constructed with fewer stitches to prevent water ingress. Its Transition Zone tech seamlessly connects the sole to the Exo Spine, accelerating response and preventing damage to the back of the boot when entering or exiting the binding.
• Velcro wings at the back of the shell can be adjusted to accommodate bigger calves and gain extra stride length when splitboarding.
• Our asymmetric 3D Molded Tongue is curved more sharply towards the medial side to match the natural ridgeline of your forefoot. This alleviates pressure points and provides a more balanced feeling of comfort and support versus a standard straight tongue.
• 3D Toebox eliminates extra layers and seams around the forefoot, improving water resistance and durablility. The streamlined design also makes it easier to slide your boot in and out of the binding.
• Shock-absorbing dynamic gel pads are inserted into the outsole around the heel area. This extra cushioning helps you soak up heavy landings and reduces fatigue from bumpy snow. It also makes your boots super comfy to walk around in.
