The official defintion of an ugg boot is a boot made of sheepskin with the wool as the lining and the leather as the outside. In Australia ugg boots and variants like ug, ugh or uggs are used generically. A trademark of UGH-BOOTS was registered in 1971 but was not enforced and generic users of the terms successfully applied for its removal in 2006.
