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. We pair this heat-moldable liner 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.

• FLEX ZONE UPPER CUFF: The flex zone upper is designed to help retain a consistent flex pattern while reducing shell distortion when flexing.
• INTUITION COMFORT FOAM 3D LINER: Built for comfort and long-lasting fit, this liner is a softer build and features both internal and external J-Bars for added ankle support and heel hold.
• INTERNAL J-BARS (LINER): Adding J-Bars to a liner helps add structure and reduce heel lift.
