UGG

    Runs Large

    UGG runs about half a size large, and the classic boot is designed to be worn without socks against the sheepskin lining. The Classic Short, Classic Tall, and Tasman slipper all wear half a size down from your usual. The lining compresses with wear, so a snug initial fit is correct. Performance and athletic UGG models fit closer to true to size.

    Sizing Verdict

    UGG runs large. Size down half a size from your usual.
