Season after season, this team favorite squashes everything in sight with plush precision and responsive control right out of the box. Setting the bar higher in every discipline is still the headline for the men's Burton Ion Snowboard Boots. Legendary sums them up and makes them an easy choice for riders who hit the entire mountain. Out-of-the-box comfort promotes a relaxed and natural stance with unmatched control for any terrain. Warm, dry, and comfortable feet are a given with heat-moldable liners that reflect heat, manage sweat, and enhance the boot's overall responsive feel. LACING: Speed Zone lacing system features lightning fast lacing control while allowing you to customize the tension of upper and lower zones in seconds. New England Ropes use American-made fibers and are virtually indestructible, won't kink, and are easy to re-lace. 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. Outer pressure relief panel. 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-moldable, 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/TRACTION: 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. SOLE: EST -optimized midsole lowers your center of gravity and improves board feel without sacrificing comfort. Shrinkage footbed reduction technology reduces the boot's overall footprint, minimizing toe drag. Burton Item Code: (3)170361
