Flex: 6 (1 Soft – 10 Stiff). The Burton Supreme Snowboard Boots are a stiffer boot perfect for backcountry pow slashes and riders who prefer a bit more support from their boots.

Thin Profile 3D Molded Tongue: Adjusting the profile of the tongue’s thickness controls its flex, enhances its ability to wrap the forefoot, and reduces shell/liner stack-up for improved comfort.

The Articulating Cuff creates a fluid forward flex by allowing the upper and lower cuff of the boot to flex independently, thus minimizing shell distortion and maximizing heel hold and response.

Whether you have funky cankles or a grotesque sixth toe, rest assured that your feet will be wrapped with comfort in Burton’s Imprint liner. While they fit great out of the box, you can even custom mold these babies to the shape of your foot with Burton’s EMU heat-molding system at your local shop.

Burton uses three levels of Power Spine backstays throughout the liner to increase medial/lateral support, edge-to-edge response, and, most importantly, durability.

Therm-ic liners are pre-wired for heat! Basix battery pack is not included with the boots. Frozen feet? Crank your slimmed-down Basix battery pack to a toasty 104 degrees. Shredding all day? The system packs enough juice to last up to 9 hours from a single charge. Basix battery pack sold separately.
