Index Boots

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.

Custom Calf. Velcro wings at the back of the shell can be adjusted to accommodate bigger calves and gain extra stride length when splitboarding.

ArmorTech. This bombproof TPU strip wraps around the front of the boot to shield it from abrasion and protect your toes when you're kicking in steps. It also prevents the boot from packing out too much, prolonging its life.

Exo-Spine. An external backstay that supports the whole boot and transfers energy instantly from heel to toe. It connects seamlessly to the outsole via our Transition Zone, so you won't hook up on the binding's heelcup when you enter or exit your binding.

Space Blanket. A thermal insulation barrier between the outsole and the bottom of the liner keeps the warmth inside and the cold outside.

3D Molded Tongue. 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 Molded Toe Box. Our 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.

ASYM 3F. A unique asymmetric boot design co-developed with BOA® that generates optimal support and flex. The asym tongue features lace guides positioned on the flatter forefoot areas for more even closure and less point-loaded pressure. Increased medial arch support reduces foot fatigue and cramps.

OC-KUSH. 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.

Storm Cover. A water-resistant PU/mesh cover with zipper. The Storm Cover keeps feet dry for long days in deep snow conditions and features a 3D engineered knit to perfectly match the shape of the boot. Stretchable material at the top eases closure.
