Comfortable, dependable, and stylish, the K2 Boundary?s unique zonal BOA® Lacing, an Intuition® Control Foam 3D Liner and a 3-Point Harness for those that like to micromanage the fit of their snowboard boot. Underfoot, a Rubber Light outsole is injected with Harshmellow? to keep you exploring new terrain, even after the lifts stop running. WHAT SIZE SNOWBOARD BOOTS DO I NEED? Please take care to measure your feet accurately. Snowboard boots are made in either US or Mondopoint (cm) sizes. For your Mondopoint Size, measure your larger foot in centimetres with your heel against a hard surface. Please consider that your usual European (EU) size, may be different in a snowboard boot. When your boots arrive, if they feel tight, don’t panic! Snowboard Boots have foam liners which will wear in over time.
