Why the UGG is so successful!

What make UGG snow boots so successful? It’s definitely a long story. It took me a little longer to get back around to the sheepskin rundown than I thought it would. It turns out that some of you took my advice, and the UGG rush has hit earlier than ever. Thanks to all of you. You're making my Christmas very merry.
So! UGG Australia and Koolaburra. When talking about "The Real Thing" in terms of sheepskin boots, a boot from one of these two companies is what people are referring to. There's a lot of legal history and bad blood between these two companies, but I couldn't find an unbiased source for information on the dispute, so I'll be leaving the politics out and focusing solely on the shoes.
This brings us to the big defining question: What's the difference? Koolaburra's are more expensive. UGG's are in higher demand. Why are both of them so much more expensive than the others? We will start with what is the same.
-Both originated in Australia, and found success in the U.S. (specifically California) prompting them to move their headquarters to Santa Barbara County in California.
- Both UGG boots and Koolaburra use twin (or double) face sheepskin. This means the bond between the sheepskin and the fleece in your boot is stronger because the fleece was never disconnected from the sheepskin.
- Both companies only use the highest quality of sheepskin in the construction of their boots.
