Flex

Medium Flex: 5 - 8 (1 Soft - 10 Stiff) – A balance of quick edge engagement and a more forgiving, playful feel. Great for all-around riders.

Fit

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.

Liner

Imprint™ 3 Liner – DryRIDE Heat Cycle™ Lining | Focus Cuff Heel Hold System with Velcro® J-Bar Interface and Inner Lace Lock | Plush Cuff 1.0 (women's only) | Lightweight Power Panels | Velcro® Liner Closure | Level 2 Molded EVA Footbed with ESS Support Shank and Aegis™ Antimicrobial Coating | Heat-Moldable

Focus Cuff – Boosting heel-hold by hugging that sweet spot around your ankle, the Focus Cuff rides slightly higher on your ankle than the Lock-UP Cuff for increased response.

Lacing System

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.

TX3 Lacing – The best of both worlds. TX3 is a flexible and low-friction textile lace used in high-power boots to provide a soft, modern design aesthetic with lasting durability and strength.

Sole

Vibram® Eco Step – Made of 30% recycled materials. This outsole has excellent grip and traction from rubber ice spikes but remains lightweight. ReBounce Cushioning, EVA and B3 Gel in the heel and toe area for extra comfort.
