DH works with a man from Australia and his wife gave me a pair of chestnut-colored Uggs a couple of years ago and they are wonderful....soft, warm, and very comfortable to wear for hours....
I already had a pair of Kirkland boots (Costco) that looked identical to them other than not having the label on the heel....my Costco ones look and feel just like the Uggs...so much so that I went back to Costco and bought a pair of black ones. Today I was there and they now have a shorter version of this boot for $ 29.99....it is 100% Australian shearling lined like the others. If you really must have the label, go for it!
I suggest trying a Kirkland pair first; if you don't like them it's no problem to return for a refund. I am told these boots are actually Uggs without the brand. They in no way look like many of the cheap knock-offs I have seen everywhere.
I shoveled snow in my Kirkland boots last year and my feet were warm and dry; I have not used any waterproofing spray on them.
