Ugg Classic Cardy Boot. EUC. Color is charcoal gray. Size 6. Smoke free home. Our Classic silhouette is recast in a warm, chunky sweater knit that's convertible based on your mood – pull all the way up the calf, slouch it down a bit, or fold all the way over for a shorter style. Three large buttons decorate the top of the shaft and three smaller ones appear when the boot is cuffed. The Cardy is lined with a plush wool insole, while our signature lightweight sole provides cushioning, traction, and durability. Pair these boots with slim pants and a leather jacket for weekend events.
