Very cute boots.  Unfortunately I was sent the wrong size(can't say whose fault, maybe I ordered UK not US?).  Anyway, I got such a great deal I kept them and gave them to a friend and she absolutely loves them. She wears a size 9(boots were a 9 US)and she said they were a tad bit small but still fit.  Like most Docs, I'm sure they will stretch a little.  Even though they are a pull on boot they are not hard to get on and off.  The circumference is a decent size, you don't have to have chicken legs to wear these.
