Got them this morning. I wear a US 8.5, ordered the UK 40. About a half size big, but that's fine, the lower fits my wide feet. I will pad them out with moleskin in the back.
EVERYONE, men and women are going OMG CUTE SHOES, WHERE DID YOU GET THEM? My fiance saw them and got genuinely excited as all get out. Another guy in my office immediately wanted to know where I got them so he can show his fiancee where to get adorable shoes. These are absolutely cinderella shoes!!
