Flex: 5 (1 Soft – 10 Stiff). The Burton Emerald Snowboard Boots are straight up the middle of the road when it comes to stiffness. If you like to do it all, the Burton Emerald Snowboard Boots are for you. All-mountain, park, and deep backcountry sessions – the Emerald doesn’t shy away from anything.

Burton’s new 270 degree Airbag Cushioning is built to withstand the impacts and cold temperatures of riding, not slam dunking.

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.

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, found 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.

Speed Zone Lacing System offers true zonal lacing control on-the-go.
