Get to the next level without buying new boots! The 2010-11 K2 Katâ™sâ„¢ sizing shims allow the little ladyâ™s snowboard boots to progress right along with her feet. Add in the warmth, comfort and support provided by a Unified shell/liner and weâ™ve got a future pro on our hands. Internal J Bars prevent heel slip while the Boa® closure system on the shell is easy for kids to adjust. In short, fit is easy with the Kat and the price for progression is right on target.
