The Burton Men's Highline Boa Snowboard Boot combines the easy tightening performance of a Boa Coiler closure system with an all terrain design for peak to park performance. Between its medium flex and lightweight construction, the Highline is ready for everything from hot laps through the rail line to powder quests on deep days. The Highline Boa uses a Boa Coiler system for easy tightening and self retrieval of the Boa cable. To tighten, simply twist the Boa dial to ideally suit your riding style and personal preferences. Plus, the Boa Coiler system comes loose once you pop the dial up, allowing you to slip out of your boots much faster than any other lacing system on the market. Leveraging Burton's Shrinkage Footprint Reduction, the Highline Boa actually has the footprint of a boot one size smaller while retaining a true fit inside the boot. This helps to reduce foot drag, which is especially noticeable on the larger sizes. Inside the boot, you'll find a heat moldable Imprint 1 Liner with integrated lacing for secure, locked in fit. The Level 1 Molded EVA footbed cradles your foot in supreme comfort, absorbing small bumps and vibrations from harsh terrain and flat landings. Additionally, the boot's Sleeping Bag Reflective Foil retains heat for added warmth on frigid days. The DynoLite outsole enhances cushioning while reducing overall weight, and it offers traction no matter how cold it is outside. Plus, Total Comfort Construction eliminates the break in period so the Highline is ultra comfy straight out of the box.
