evo.com | Nidecker Snowboard Boots > Nidecker's flagship boot and their stiffest offering, the Nidecker Index Snowboard Boots are built for expert riders who want maximum energy transfer and zero compromise. Dual BOA(R) H4 Coiler dials give independent control over upper and lower zones, while the Internal Heel Lock uses a BOA(R) side-dial to cinch an internal harness for true three-dimensional lockdown with no heel lift. A stiff flex, Vibram Approach outsole, and Storm Cover to keep snow and moisture out - this is the boot for dedicated riders who need their gear to keep up. Asym 3F Part of the ASYM3F Technology : FIT - FEEL - FLEX are combined in an asymmetric shape and closure system that delivers optimum support and flex. Lined up along the asymmetrical molded tongue, the Boa(R) Fit System lace guides are also asymmetrically positioned on the flatter areas of your forefoot for less point-loaded pressure and a more even closure, which increases medial arch support to reduce foot fatigue and cramping. This Nidecker innovation is codeveloped with and approved by Boa(R). 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. Vibram(R) Approach Outsole This top-of-the-range outsole comes with a full EVA midsole for the best possible comfort under the whole foot. An OC-Kush insert gives excellent dampening under the heel. The highlight is the new Vibram ICE-TREK compound, which is the best rubber available for cold, icey or snowy surfaces. Extra grip at toe and heel was inspired by fish scales. Diamond Liner Made from state-of-the-art memory foam, it delivers a secure, custom fit with more consistent forward flex. 1:1 Lasting This new new last is the keystone of the boot - the best fit in snowboarding today. Nidecker landed on an 8deg forward lean - the sweet spot between comfort and performance. 1:1 Lasting means a specific liner, shell and footbed for each full and half size.
