Drawing from the legendary freeride performance of Burton's Imperial Boot, the Burton Men's Photon Boa Snowboard Boot dials in a precise, ultra powerful fit with its Dual Zone Boa closure. Instead of using traditional wire lacing within the Boa system, Burton collaborated with New England Ropes for a more natural flex and feel. And to ensure long lasting performance, New England Ropes stands by its laces with a lifetime warranty. Independently tightening over the upper, lower, and Achilles, the Dual Zone Boa with Lockdown Tech provides a truly custom fit on the slopes. Keep the upper slightly looser and the lower tighter for a bit more freedom or tighten both for the utmost in power and precision. Either way, it's totally up to you, which is the way Burton intended. Lockdown Tech eliminates lift along the Achillesheel, ensuring you're locked into the boot when you're carving at high speeds and charging steeps. Inside the boot, the Imprint 3 liner features an optional J Bar interface for extra heel hold, should you opt for the most locked down fit and feel. This thermo moldable liner provides a custom fit without nasty pressure points. The pre curved Rad Pad relieves pressure along the instep, which is where the boot's laces exert the most pressure. Moreover, the liner's Aegis antimicrobial coating prevents funky smelling microbes after long days on the slopes. Cushioning your feet from cliff drops, choppy snow, and high speed vibration, the boot's B3 Gel Cushioning dissipates impact and vibration from fatiguing your feet. The low profile EST Midsole lowers the boot's profile, boosting board feel for higher levels of control. Additionally, the rugged Vibram EcoStep features Ice Spikes for tenacious traction when you're traversing iced over parking lots and climbing steep terrain.
