The most common foot size that I dress is an American size 9 (European size 40). Size 9s are fairly easy to find, but things get tricky from thereon upwards. A subscriber to my blog has shared information with me about a solution to this very problem. She has a daughter with a size 12 foot and they battled to find pretty shoes until they discovered Kathryn Kerrigan, an online store for tall women.
Sizes range from 6-12 and prices seem reasonable. If you are tall and need a size 12 shoe, or if you know somebody that does – the above site might prove useful.
