Those who appreciate the balance of medium flex tweakability and comfort should step to the men's Burton Swath boot. Its Ultraweave shell material eliminates the need for bulky seams, allowing for super-lightweight form-fitting performance. The Dual Zone BOA® Fit System with Coiler™ Technology allows for precise 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® lifetime guarantee. Built-in Sleeping Bag heat-reflective foil stokes warmth just beneath your feet to keep the interior warm, while ReBounce cushioning ensures everything stays soft and cushy even in sub-zero conditions.
