Combined with a stiff 8 Flex rating and perfectly lasted internal fit, the Burton Ion Snowboard Boots are lean, mean, line destroying machines built for the aggressive rider.

TECH SPECS

• Flex Rating: 8 (1 Soft - 10 Stiff) – A stiff flex for powerful responsiveness and support.

• GripLITE Backstay – Snugging up the fit between boot and hi-back, our new rubber print backstays also shave weight and enhance material-to-material grip. The result of this printed rubber application is more direct transfer from boot to binding to board for reduced rider fatigue.

• Firm Flex PowerUP Tongue – The tongue on these snowboard boots is firm and dense. In exchange, you are granted with greater rebound, support and a longer lasting boot.

• Outer Shell Pressure Relief Panel – Ultra-soft gel cushioning is fused to the area where the ankle strap rests on the boot for even pressure distribution when bindings are cranked tight.

• Infinite Ride™ 4 Liner – Sewn liners are an industry standby and that's why Burton decided to break the mold with its stitch-less technology. Built with a 3D molding process, the Infinite Ride™ liners elevate out-of-the-box consistency for a precise fit while also enhancing the ride with greater rebound and cushioning that won't break down or pack out. They are infinitely heat-moldable, and the new asym Velcro closure creates even better wrap at the top of the liner.

• Total Comfort Construction – Get an instantly broken-in feel right out of the box. Total Comfort's industry-exclusive construction eliminates the break-in period for a fit that feels just as good from opening day to day 100.

• Aegis™ Antimicrobial Coating on Liner.

• DRYRIDE Heat Cycle™ – Heat Cycle™ lining is extremely breathable, lightweight and utilizes interwoven thermally activated carbon threat to capture, radiate and reflect heat inward. In translation, it is designed to keep your feet warmer as it wicks heat-robbing moisture outward for all day comfort.

• Tuff Cuff – Burton's Tuff Cuff provides you with more ankle support and inner cuff stability. This is a feature designed for pro-level boots. Tuff Cuff also increases heel hold and wraps the ankle with medial and lateral support without sacrificing flex or comfort.

• Speed Zone™ Lacing System – Lightning fast lacing control at its finest. Customize the fit of the upper or lower zone in seconds; because the system is so powerful, you get more rebound, more wrap and better response, all with less effort.

• Level 2 EVA Footbed – EVA Footbeds are lightweight, long-lasting and absorb shock.

• Sleeping Bag Reflective Foil – This low-profile and lightweight underfoot technology reflects heat back to the feet, improving both warmth and comfort when faced with cold conditions.

• Low-Profile EST® Optimized Midsole – EST® goes beyond bindings by optimizing the soles on select boots for a more direct connection. Lower-profile, lighter weight, and with a reduced ramp angle, EST lowers your center of gravity and improves feel. All without sacrificing an ounce of cushioning thanks to ultra-dampening B3 Gel inserts.

• AutoCANT Cushioning – Dual-density EVA allows your foot to settle into a more natural and relaxed position, resulting in improved comfort, reduced fatigue, and smoother, more direct board control.

• ReBounce Cushioning – More comfort and more warmth is the Burton-exclusive benefit of ReBounce Cushioning. The extra hops are accomplished by surrounding the foot with a two-layer 3D laminate of cushy PU plus reflective material, which not only reduces impact and absorbs chatter but also turns heat inward.
