We got Emu Australian sheepskin boot at TJ Maxx for a good price - they were still expensive (close to $100) but less than the comparable Ugg brand. I looked up the Emus
http://www.sheepskinbootsforyou.com/emuaustralia.htm and Uggs online, (
http://en.wikipedia.org/wiki/Ugg_boots). Apparently "ugg" is used in Australia as a generic word for sheepskin boots, which includes the Emus, though the Ugg brand is copyrighted in the US.
DD loves the boots, but a month ago some girls at her school were B****y because DD's boots didn't have the Ugg label. They kept teasing her during several periods and made her miserable.
Much as I'd hate to say you should the "right" brand even if it's more expensive, you might want to consider it if a lot of that kind of teasing goes on at her school and if you think she might not be able to just ignore it.
