Product Info

The K2 Boundary Snowboard Boots feature a looser, surfy feel, but they can still dial it down and crush techy lines if you need them to. They exist right on the boundary between tight and loose. For riders who like to style it out in the park, but also hike to hidden stash spots just out of bounds, this boot has your name on it. And if you yourself happen to exist somewhere on the boundary of "fun at parties" and "this dude is truly wild," you might want to check them out in the exceptionally fun and flirty Party colorway.
