The Index is our flagship freeride boot, built for limitless backcountry adventures. It features the very latest Nidecker technology and dials up the stiffness for pure big mountain performance, whether you’re hiking lines off the lift or splitboarding into untouched terrain. We’ve constructed it around an asymmetrical upper that conforms perfectly to your foot and calf, with flex zones for unrivalled control without sacrificing comfort. A water resistant Storm Cover provides extra shelter for your feet and keeps your laces from icing up in deep snow. The lace system itself is BOA’s top-of-the-line H4 Coiler, with a brand new Internal Heel Lock system operated via the side dial and a separate control on the tongue to tighten the shell.
Expect unreal comfort and foot hold. To maximise grip in frozen terrain, we’ve added a premium B.F.T Vibram Approach outsole featuring an Icetrek rubber compound, while dual EVA layers in the midsole reduce vibrations on bumpy terrain and help soften big landings. The outsole blends into the Exo Spine via our seamless Transition Zone design, eliminating the chance of snagging the back of your boot on the binding and boosting heelside response. The solid feel continues up front with a tough TPU shield we call ArmourTech, which protects your toes while you’re kicking steps up that ridgeline. Inside, a Gold Level Wrap Liner provides unparalleled comfort and support, and can be heat moulded for a custom fit. Make no mistake, this thing is the absolute pinnacle of boot technology. From Japanese tree lines to that dream Alaska trip, the Index is expedition-ready.
Closure
Hybrid Tongue Closure
The BOA® Dial, located on the tongue, pulls together the upper and lower part of the boot. Then the BOA® dial on the side activates a double lace that runs through an internal harness connected to the shell and tongue. When tightened, it creates a locking sensation and provides 3D heel lockdown. On both sides, lateral locking is done via the ankle strap and frontal locking is done via the laces that run through the tongue and tighten the tongue towards the instep.

Heel Lock
Internal Heel Lock
Say goodbye to heel lift. An internal harness attached to the shell and tongue is tightened via the external BOA® side-dial. Laces enter from both sides and travel through the tongue section, firmly enclosing the ankle while pulling it back into the boot for incredible, three dimensional foot hold.

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.
