The K2 Rosko is a snowboard boot that is much more than you bargained for, and a noted over-achiever in the K2 snowboard boot collection. Built with the tech you need from companies you trust, they 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.
