Flex Rating: 7 (1 Soft - 10 Stiff) – A medium-stiff flex for responsiveness and support.

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

Rad Pad – The pad is located on the top of your instep, right where the internal laces exert the most pressure, a Rad Pad has pre-curved panels for extra comfort, support and long-wear.

Firm Flex PowerUP Tongue – For greater rebound and durability, the majority of Burton's boots feature this dual density tongue construction. Like all Thin Profile 3D® Molded Tongues, it's available in one of three flex options based on the boot.

S4 Shell Panels – Start strong, stay strong. Superlight and resilient, these shell panels on the Imperial evenly distribute strap pressure to maximize rebound and resist breakdown for consistent flex, season after season.

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 – Antimicrobial coating uses small silver and sodium fibers to prevent odor causing bacteria from growing.

Imprint™ 3 Liner – Focus Cuff Heel Hold System with Velcro® J-Bar Interface and Inner Lace Lock // Plush Cuff 1.0 // Sock Lock // Rad Pad for lace comfort // Velcro® Liner Closure // Level 2 Molded EVA footbed with ESS Support Shank and Aegis™ Antimicrobial Coating // Heat-Moldable

New England Ropes – American-made, natural fiber ropes power Burton's Speed Zone™ systems. Virtually indestructible, New England Ropes' laces are the same stuff used by stunt men, firefighters, and rescue teams.

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.

ESS Support Shank – This is an added support feature to help soften hard landings.

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.

Vibram® EcoStep™ – 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.

B3 Gel – In the heel, B3 Gel dramatically dampens vibrations and absorbs impacts. Formulated to withstand repeated impacts without breaking down or hardening up in cold temperatures.

EST® Optimized – 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.

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.
