I've read mixed reviews on their sizing... I typically wear a 38 in Euro sizing ~ Louboutin, Zanotti, Valentino, Choo, Prada, Charlottle Olympia, etc., Via Spiga is 7.5.. I think those are the only US sizes that I own. J Crew is a 8. I hope that helps. The only place that I have found them in my size is from a store in Canada so I want to be sure to purchase the correct size. Thanks in advance!
