This is my first pair of Uggs (my second is on their way to my house as I type!).  Let me start by saying that I usually wear a size 9 or 9.5.  I ordered a size 8 in these, as suggested to size down, and they fit PERFECT.  They are comfortable, warm and I get compliments on them everywhere I go!  I have the gray ones and loved them so much that I ordered the black ones.
