I like these Danskos, but I am returning them and ordering a size up.  I wear a size 8.5 or 9 in all other shoes, and I ordered the 39, but they fit too snugly over the top of my feet.  I tried them on in the morning when my feet are less swollen, and also in the evening when my feet are a little swollen and tired from standing all day, and I'm convinced I just need to size up to a 40.

They are, however, well-made and appear to be true Danskos.  My other complaint is that they make me really tall, as I'm 5'8" already, but that is something I think I just need to get used to since I'm used to wearing flats around the hospital.
