2025 K2 Rosko Snowboard Boots
The Rosko was built to surpass all your boot expectations, it’s been purpose-engineered to be a noted overachiever in K2’s collection. Built with the tech you need, from a brand you trust, we’ve partnered with BOA® and Intuition® to give you the best bang-for-the-buck.
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. K2 pairs this heat-moldable liner with their easy-to-use Fast-In liner lacing for a premium fit.
K2 ties 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.
