The Radical Pro is uniquely designed to offer you the velocity and seamless glide typical of a racing skate, combined with the trusted comfort and support associated with the K2 Softboot. Featuring all the attributes of its Radical counterparts, it also incorporates our innovative Radical Hi-Lo frame and Carbon Radical Cuff (the very cuff that secured 15 Medals for Madshus athletes during the 2006 Winter Olympics). It is ideally suited for extended training sessions, marathons, and virtually any locale where speed enthusiasts wish to glide.
