UGG snobs may believe they are knockoffs, but they are not; these are genuine UGGs manufactured by a firm recently bought by UGGS. There is no discernible difference in the appearance or feel of the boot. In fact, even the inside of the boot is made of the same material as an UGG. They look like every other boot from any other brand and that's what makes them so popular. The fact that they look like regular UGGs helps them to sell in large quantities and at low prices. However, although they are cheap, they don't last long because the materials used are not as durable as those used by UGG. The Koolaburra boot was originally designed for use by Australian aborigines who lived in sub-tropical climates. The boot features a soft upper made from sheepskin with a hard plastic bottom for support. The outsole is also made of plastic. In 2000, a company called "Ugg Australia" started manufacturing these boots under license from UGG. They are sold under several different brands including Koolaburra and Roamalama. There are some people who claim that the Koolaburra boot is not a real UGG but instead it is a copy of a copy. However, this is not true.
