Comfortable, convenient, and full of next-level features, the K2 Kat Boot ensures that the groms get the most out of their snowboard boots. Engineered with the grom's (and their parents') best interest in mind, the Kat Boot features the easy-to-use Youth Boa Fit System so the little ones can adjust to the perfect fit completely on their own. A Comfort Foam EVA Liner delivers warmth and out-of-the-box comfort, and features internal J-Bars for added ankle support. And to ensure the boots get more than one season of use, the adjustable Grows-A-Long Shims can be extended to adapt to growing feet. No matter the skill level or riding style, the K2 Kat snowboard boots make progression comfortable and fun.
