|Lacing System||Dual Boa®|
Setting the bar higher in every discipline, the Burton Ion Boa boot is the only men's model to feature the Hi-Power Focus Boa Fit System, the pinnacle offering for effortless, precision fit. Built to charge hard across the entire mountain, the Ion is legendary for its stacked tech package, and upgraded with our Life Liner for lightweight comfort and enhanced rebound. The full feature list includes AutoCANT EST® soles for natural lower-body alignment and superior board feel, DRYRIDE Heat Cycle™ for enhanced warmth and moisture wicking, and ReBounce tech that reflects body heat and cushions consistently in freezing conditions.
Stiff Flex: 8/10 – Aggressive and responsive, a stiff flex is made for quick edge engagement and control at speed.
1:1 Firm Flex PowerUP Tongue – Burton offers 1:1 lasting on every boot. It means every half and full size shell, tongue, and out sole offer a precise fit that is not as common as one would think. Drop your loot on a Burton boot and you won't be stuck with the slop of a mismatched shell and liner. PowerUP tongues feature additional dual-density material for rebound and durability.
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 day 1 to day 100.
Outer Pressure Relief Panel – Ultra-soft cushioning is fused to the area where the ankle strap rests on the boot for even pressure distribution when bindings are cranked tight.
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 construction provides a combo of cat-like quickness and long-term resistance to breakdown, while also accommodating a better fit for all foot shapes.
DryRide Heat Cycle™ Lining – Warmth and wicking are two key traits for on-snow comfort. Burton's breathable inner-lining technology utilizes interwoven thermally activated carbon thread to capture, radiate, and reflect body heat inward to keep feet warmer while also wicking heat-robbing moisture outward. Look for varying amounts and performance level of each liner.
Tuff Cuff – 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.
Dual Zone Boa® System with Coiler™ Technology – All Burton men’s, women’s, and youth boots with Boa® feature the virtually indestructible, Warrantied for Life performance of Burton‑exclusive New England Rope laces. Built with a redesigned inner Coiler spool to route the laces, the dial‑it‑in system retains its quick, easy, and effective lace adjustment. Natural fiber ropes equal a more natural flex and feel for greater all‑day comfort.
Boa® System – A highly dependable lacing system that can be adjusted at a moment's notice anytime, anywhere. The simple twist of the knob at the top of the boot strategically tightens in just the right places.
TX3 Lacing - Durable and strong.
EST® Optimized Midsole – EST® goes beyond bindings by drawing inspiration from the surf/skate heritage of snowboarding and giving you a more direct connection to your board. By eliminating the ramp angle of your outsole, EST lowers your center of gravity, improves board feel, and creates a more surf/skate-like feel. All without sacrificing an ounce of cushioning thanks to ultra-dampening ReBounce and B3 Gel inserts.
ReBounce Cushioning – Brings cushioning closer to your foot than ever before by placing it within the shell of the boot for an added layer of impact protection that sits directly below your foot. Added warmth and consistent performance in cold temperatures is achieved by wrapping it in a heat-reflective material that keeps the cushioning soft and effective.
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.
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.
Shrinkage™ Footprint Reduction Technology – This 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.
Snow-Proof Internal Gusset – All Burton boot tongues feature an internal gusset construction to completely seal the lower zone of the boot, keeping your feet warm and dry.
