The Ugg Australia Classic Cardy have knit uppers and a sheepskin lining. On the back of the Cardy Boots, there is a suede heel guard which provides durable wear all season long. The Classic Cardy is detailed with three oversized wood buttons, allowing to be styled up and buttoned, slouched and slightly unbuttoned, or completely cuffed. These will look fab with skinny jeans in winter and a big chunky jumper.
