I wear a 7 in most shoes.  I bought two of these UGGs in 7's and they were way too tight.  Couldn't even get my feet in them without bulging veins.  SO I ordered two more in size 8, one of them from this order and Amazon seller.  Well, the 8 is still tight on my size 7 foot! I can get my foot in it without my veins bulging out, but it is still tight.  ANd way too small for a size 8.
