The K2 Men's Lewiston All-Mountain Snowboard Boots are highly-responsive, mid-flexing boots perfect for intermediate to advanced riders. They feature an articulating cuff that helps eliminate shell distortion and a 3-Poit Harness wrapped around heat molded Intuition® Control Foam 3D Liner for an unreal fit that also keeps you warm, dry, and comfortable. And to top it all off, K2's new RollSole outsole yields extra mobility in a best-of-both worlds package along with rubber for performance and phylon for weight reduction.
