I bought a size 7.5 which is usually a half size larger for me, but I prefer a little room in high heels.  These were a very snug fit, so I definitely think the sizing is off.  While I like the comfortable foot pad and the sole, I do think the patent leather is too stiff and it would take a lot of breaking in for them to be comfortable for me (even in a bigger size).  And so despite its nice look, I decided to return.
