I love, love, love these boots!  I feel that if I would have ordered a UK 7 they would have been too small, so I ordered a UK 8.  I usually wear a US size 10.  These boots have plenty of room to spare.  I can wear them with a thick sock and they are comfortable.  With a thin sock, they have a lot of slippage going on.  Not so great for wearing them with baby doll dresses in the summer, but I am overall happy with my purchase.  I will wear them for years to come.
