The K2 Rosko is a snowboard boot that is much more than you bargained for, and a noted over-achiever in our snowboard boot collection. Built with the tech you need from companies you trust, we partnered with BOA and Intuition to give you the bang-for-the-buck you are after. The H4 Coiler BOA Fit System uses stainless steel BOA laces to provide a secure closure with an effortless twist of a dial. The integrated Intuition Comfort Foam 3D liner naturally forms to the shape of your foot, and is constructed with internal j-bars to hug and cushion your ankles. We pair this heat-formableliner with our easy to use Fast-In liner lacing for a premium fit. We tie it all together with a Phylite outsole and integrated flex zone upper cuff for grippy, lightweight, durable performance and smooth flex over the lifetime of the boot. CATEGORY: Lace.
