Plush and responsive, it's all systems go with the Ion BOA Snowboard Boot. Season after season, the Ion sets the bar for responsive feel and out-of-the-box fit. The men's Burton Ion BOA Snowboard Boots take it one step further with high-power micro-adjustable tensioning for the upper and lower boot. Combined with a firm flex, they support full-speed-ahead charging for riders who like to rip. Warm, dry feet and unmatched control for dropping lines and sticking landings are all yours.

It's full-speed-ahead with this boot's firm flex. A Dual-Zone BOA Fit System lets you independently micro-adjust the fit and feel of the forefoot and upper boot for the just the right fit and feel. The Ion features BOA dual high power system for more tensioning power and control of the instep and lower zone than other BOA systems.

FEATURES:

• Lacing: dual-zone high power focus BOA fit system with coiler technology, featuring two distinct lace zones that can be independently allowing for powerful tensioning and a custom fit in the upper and lower portions of the boot
• Flex / response: welded backstay increases support and durability, 1:1 firm flex powerup tongue creates a snug fit between boot and tongue, eliminating the need to readjust while you ride
• Comfort: total comfort construction provides an instantly broken-in feel right out of the box, eliminating the break-in period, snow-proof internal gusset completely seals the lower zone of the boot, keeping your feet warm and dry
• Liner: tuff cuff lite increases heel hold and wraps the ankle with medial and lateral support and also enables free flex from heel to toe.
• Life liner uses heat-mouldable, lightweight materials for high-end performance with a relaxed feel and features a responsive PU tongue for a combination of quickness and resistance breakdown that excels during long seasons of hard riding
• Dryride heat cycle lining captures, radiates, and reflects body heat inward to keep feet warmer while also wicking away heat-robbing moisture, ultralon performance foam has excellent thermo-forming ability, adapting the boot liner to the contours of the foot
• Cushioning: sleeping bag reflective foil underfoot reflects heat back to the foot, improving both warmth and comfort in cold conditions
• Autocant cushioning uses dual-density EVA that lets your foot settle into a natural, relaxed position for improved comfort, reduced fatigue, and more direct board control
• Rebounce brings cushioning closer to your foot by placing it within the shell of the boot for an added layer of impact protection sitting directly beneath your foot
• EST-optimized midsole lowers your centre of gravity and improves board feel without sacrificing comfort, shrinkage footbed reduction technology reduces the boot's overall footprint, minimizing toe drag
