With a legacy of pushing personal skills to the pro level, the Burton Ruler boot is the boot for stepping to larger drops and burlier features. For riders seeking Ion-level performance but lack the loot. The Dual Zone Boa® System Featuring Coiler™ Technology allows for quick forefoot and upper boot adjustment with a simple twist of the dial, and the long lasting performance of Burton-exclusive New England Rope laces with the Boa Guarantee. 3M™ Thinsulate™ Insulation in the liner and the added warmth of our Sleeping Bag heat-reflective foil defies arctic blasts. The medium flex PowerUP Tongue resists breakdown, and maintains a steady ride from one day to the next.
