As the name suggests, the K2 Radical X Boa is equipped with the Boa Closure System, which nobody should live without. The K2 Radical X Boa combines the high speed and smooth roll of a high-end race skate with K2's comfortable softboot technology. We have affectionately named this skate the "citizen" race skate because comfortable and supportive boot makes the race ready wheels/frame/bearing combo accessible to the average Joe. In other words, no more painful blisters and zero ankle support associated with traditional racing skates. This super light skate has all the features of its Radical 100 cousin along with K2's new Radical Hi-Lo frame and carbon Radical Cuff (the same cuff that won 15 medals on Madshus athletes in the 2006 Winter Olympics.) It's perfect for long training skates, marathons and anywhere else speed junkies want to roll.
