I wear a size 6 and have a wide foot which can cause fitting problems.  The Puma Zandy flat in black patent (with a pink logo) fits well.  While a little tight initially across the instep, on my second time wearing them I ended up on an impromptu three hour hike in the Tucson desert with a girlfriend.  No problemo!
Comfortable, stylish and a great little flat for straight leg/ankle/cropped jeans.
