I have the black ones and I got them in size 8, although my regular shoe size is 7.5, so they do run a bit small as suggested in the other reviews.  They are very light weight and very comfortable.  They are a bit sporty, but I think I could get away with wearing them at work too.  They are great on the weekends with jeans, and I have received a lot of compliments on them.  I have trouble finding comfortable flats, but these are great!
