The Ugg Classic Cardy is a heathered merino wool blend boot made to look like your favorite sweater. Three wooden buttons etched with the signature UGG logo allow this boot to be one of our most versatile and refreshing styles. Slouch the boot down, cuff it over or wear it all the way up for varied style. All boots in our Classic Collection feature a soft foam insole covered with genuine sheepskin and have a molded EVA light and flexible outsole designed for amazing comfort with every step.
