The Cadillac of snowboard boots, Burton Ion boots are made to deliver maximum comfort, warmth, and performance. These boots use Burton's ultra-reliable Speed Zone™ Lacing System so all you have to do is pull on the tabs and then tuck them away in their pockets before taking the lift to the top. The leather outsole will outlast any other and just becomes more comfortable season after season. That being said, it's also treated with Burton's Total Comfort Construction which ensures you won't have to go through a crazy break-in process like you did in the old days.
Since this boot has a true 1:1 fit, just go with your normal shoe size and let the heat-moldable LIFE liner do all the work for you. You'll love how the Power Up tongue responds quickly yet breaks down slower than molasses. The liner has DRYRIDE material for moisture wicking warmth retention continuously cycling your body heat throughout the liner. Reflective foil is added in the bottom of the boot because of the same, heat-retention properties. A level 2 Molded EVA Footbed is the first line of defense against chatter. This combined with AutoCANT cushioning, ReBounce Cushioning, and an arch support called ESS support Shank all work together to make you feel like you're riding down the mountain in your most comfortable slippers. In fact, owners of Ion boots often wear there liners as slippers when they get off the hill because they really are that comfortable. That's why the liner has grip on the bottom.
Speed Zone™ Lacing System - The Speed Zone™ Lacing System features streamlined, profiled lace guides for increased performance and improved durability. The system retains lightning fast lacing control by allowing you to customize the fit of the upper and lower zones in seconds. More power means more rebound, wrap and response with less lacing effort.
New England Rope laces add a virtually indestructible character worthy of Burton's Lifetime Warranty.
DRYRIDE Heat Cycle™ Lining - Dryride Hyperwick mesh in the toe box both insulates and regulates warmth by pulling moisture away from your skin, then evaporating it through a waterproof/breathable shell membrane. Like a one-way door, the microscopic pores in this membrane allow moisture vapors to escape, while water droplets from the outside can't enter.
ReBounce Cushioning Underfoot - More comfort and more warmth is the Burton-exclusive upgrade of Rebounce Cushioning. The extra hops are accomplished by surrounding the foot inside the shell of the boot 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.
Sleeping Bag Reflective Foil Underfoot - This low-profile and lightweight foil underneath your liner reflects heat back to the feet, improving both warmth and comfort when faced with cold conditions.
Shrinkage Footprint Reduction Technology - Shrinkage reduces the boot's overall footprint one full size, meaning a men's size 10 fits like a size 10, but has the footprint of a typical size 9. Shorter, lighter, sleeker. Never suffer from toe drag again.
Low-Profile EST Midsole Design - Lower profile, lighter weight, and with a reduced ramp angle, EST optimized soles lower your center of gravity and improve feel. Control your setup like never before without sacrificing an ounce of cushioning thanks to ultra dampening B3 Gel inserts.
EST goes beyond bindings by drawing inspiration from the surf/skate heritage of snowboarding and giving you a more direct connection to your board.
Life Liner - The Life liner fuses lightweight materials with a more relaxed feel for high-end performance that makes all the difference during long seasons filled with hard charging days. The responsive PU tongue provides a combo of cat-like quickness and long-term resistance to breakdown, while also accommodating a better fit for all foot shapes.
Tuff Cuff Liner Wrap - Ankle support and inner cuff stability is mandatory in a pro-level boot. Burton's solution is the Tuff Cuff, which increases heel hold and wraps the ankle with medial and lateral support while still flexing freely from toe to heel.
Aegis Antimicrobial Coating - Inhibits foul odors. Your feet (and your friends) will thank Burton for sure. Look for Aegis on select liners and footbeds.
Outer Shell Pressure Relief Panel - Ultra-soft gel cushioning is fused to the area where the ankle strap rests on the boot to evenly distribute pressure when bindings are cranked tight.
PowerUP Tongue - This dual density tongue offers greater response than the previous Thin Profile 3D Molded tongue with improved rebound and durability.
Snow-Proof Internal Tongue Gusset - All Burton boot tongues have been upgraded with an internal gusset construction to completely seal the lower zone of the boot, keeping feet warm and dry.
AutoCANT Sole Cushioning - Dual density EVA allows your foot to settle into the most natural and relaxed position, resulting in improved comfort, reduced fatigue, and smoother, more direct board control.
EVA Sole Cushioning - Lightweight and long lasting shock absorption to reduce foot fatigue from vibration and harsh landings. Keeps you riding longer and stronger.
Total Comfort Construction - Get an instantly broken in feel right out of the box. Total Comfort's new industry exclusive toe box construction eliminates the break in period for a fit that feels just as good from shop floor to season opener, and every day thereafter.
1:1 Boot Lasting - Every Burton liner is factory molded with the "Last" inside the shell to ensure a superior, out-of-box fit with precise, liner-to-shell integration. 1:1 lasting means that every half and full size liner gets a matching half and full size shell and outsole for the best possible fit with the smallest possible footprint.
1 Year Warranty - Covered under manufacturer warranty for 1 year from the time of purchase. Warranty includes manufacturer defects in materials and workmanship only and DOES NOT cover damage due to normal wear and tear, damage from resting your board's edge on your boot while on the chairlift, or damage caused by any modification done outside the manufacturer's facility.
