I have a pair of ugg slippers that I only wear when the weather turns cold. Putting them on this year they feel a bit tight. Since it has been a whole year since I last wore them I cant recall if this is how they usually feel or if my ever so slightly swollen pregnant lady feet are to blame. I ask because I am planning on ordering a new pair and would like to get the right size. There is no place close to me that sells them in store so I was going to order online. I normally wear an American size 8 1/2 to 9 and these are 9's....what size do you ladies usually get in Ugg slippers? You think I should go up to a ten or would those be too big?
