The name ugg boots is derived from that famous Aussie tradition of lovingly abbreviating every common usage term, and it was only a short skip from "ugly boots" to seriously "ugg boots". Ugly as they were perceived at the time compared to more traditional wear, there was no beating these Australian uggs boots for warmth and comfort.
How the rest of the world started getting in on the action is somewhat debated, but one of the most commonly held beliefs is that they were popularised by Baywatch star, Pamela Anderson, when she kept her feet warm on set by wearing a pair of Australian ugg boots. Since then, tens of thousands of people around the world have bought pairs of uggs, whether it be as Aussie souvenir gifts, fashion statement, or most commonly, for their pure comfort and enjoyment.
