The Burton Men's Ruler BOA® Snowboard Boots give riders time-honored tech, comfort, performance and the dialed fit of the Dual Zone BOA® System featuring Coiler™ Technology. These boots offer an overall medium flex and responsive feel, raising the bar on board control while their EST® optimized midsole lowers your center of gravity and improves board feel without sacrificing comfort. They feature a Dual-Zone BOA® Fit System with Coiler™ technology with two distinct lace zones that can be independently adjusted with the twist of a dial for a custom fit in both the upper and lower portions of the boot. To give you the most comfortable experience, Burton has designed these boots with a durable synthetic backstay, lock-up cuff and a Total Comfort Construction that provides an instantly broken-in feel right out of the box, eliminating the break-in period. Warmth is provided mainly by two technologies: the sleeping bag reflective foil underfoot that reflects heat back to the foot, improving both warmth and comfort in cold conditions, as well as the Imprint™ 2 heat-moldable liner that features 3M™ Thinsulate™ insulation for low-bulk warmth and an inner lace lock with a hook-and-loop closure for a snug fit. Enjoy snowboarding like never before with the Burton Men's Ruler BOA® Snowboard Boots!
