The boot that's elevated more riders with time-honored tech, fit, and performance, now features the dialed fit of the Dual Zone Boa Fit System with Coiler Technology. 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 who lack the loot, the Dual Zone Boa Fit System with Coiler Technology allows for effortless micro-adjustability. Forefoot and upper boot fit are controlled with a simple twist of the Boa dial, all with the long-lasting performance of Burton-exclusive New England Rope laces and the Boa lifetime 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.
