I do think the article/warning on Ugg fake boots is enlightening. I want to add that buying, by mistake, a pair of fake UGG boots was a complete waste of money. It wasn't just the 'label' and excellent appearance I wanted - but the fake boots were not SAFE to walk in wet streets. Almost dangerous in that the soles have no grip at all. And, having turned them into 'house' boots the seams came apart soon after a short time. I talked with a friend wh also been duped by the idea of having a bargain, and she had the same experience - especially that they were not safe to walk in outside.
UGG (R) Australia are worth the money - I have two pairs - one for about 2 years - and another for 5 years. I am now about to buy an extra pair - but I shall always only use the UggAustrialia.co.uk, or recommended retailers.
