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.

Key Features

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.
