evo.com | Nidecker Snowboard Boots > The Nidecker Altai Wide Snowboard Boots deliver the same confident, all-mountain feel as the original Altai, just with extra room through the forefoot for a more relaxed, pressure-free fit. A supportive flex and comfortable liner keep things locked in and ready for long days, whether carving groomers or hunting soft snow. Built for riders who want performance without squeeze, especially when standard fits feel a little too snug. 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). Gravity + Made out of lightweight and durable EVA, Nidecker shaped the lugs in the same way as the rest of our outsoles - by taking cues from mountain play-grounds, then adapting them to give you as much grip as possible Transition Zone A molded connection between the boot outsole and upper shell that smooths the flex point where the boot meets the binding. It prevents hard edges from catching in the binding heelcup and improves board feel during entry, exit, and riding. Moldable Liner A general memory-foam liner that can be heat-molded in-store or naturally shaped over time to match your foot. It reduces pressure points by conforming closely to your foot anatomy as it breaks in. Flex Rating Mid-Stiff 6/10 | Nidecker Altai Wide Snowboard Boots 2027 - 9.5 in Black
