Burton Ruler Boa Snowboard Boots - Mens 20/21: 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.
