With a tradition of elevating personal skills to a professional level, the Burton Ruler Boot is designed for bigger drops and more robust features. It is ideal for riders seeking Ion-level performance without the high cost. The Dual Zone Boa System with Coiler technology allows for quick adjustments of the forefoot and upper part of the boot with a simple turn of the dial, complemented by the durable performance of the exclusive Burton New England Rope laces with the Boa guarantee. The 3M Thinsulate insulation in the lining, along with the additional warmth of the sleeping bag-like, heat-reflective foil, withstands arctic cold snaps. The medium-flex PowerUP tongue resists wear and ensures a consistent ride from one day to the next.
