I had a pair in black patent ... I usually wear an 8.5 in American brands, but find I take in between a 39 and 39.5 in CLs; I chose a 39.5 in this style.
i love these, i've been hunting a perfect pair down to replace my over worn black patent ones... good luck with your hunt! you might wanna call the major departmental stores up to check.
try the CL boutiques first, chances of them having it are higher than the departmental stores, i've called Saks Boca they didn't have them. good luck! i got mine from paris last winter!
