The men's Burton Ruler BOA® Snowboard Boot black is the boot for stepping to larger drops and burlier features. For riders who seek Ion-level performance but lack the loot. 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. The Dual Zone BOA® Coiler Closure System 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.
