This is my second pair of the UGG K harwell boots that I have purchased (I got another color earlier) and I really love these boots.  I wear a 7.5 womens in most shoes and my foot tends to be on the narrow side, but not too much.  Both of the K Harwell have fit well.  These boots are super comfortable and warm.  I get compliments on both boots whenever I wear them.  Great boots!  Hope this helps deciding.  This is a non rewarded review, just trying to help others as I read reviews before I purchase on amazon and really appreciate the people that give honest reviews about the products they purchase.
