The Fielding flat by Dr Scholl's is such a great comfy flat!  Generally ballet-style flats are hard to wear all day as a teacher, but this one had some arch support, so I wore it all day without problem. Based on other reviews I read, I ordered my normal size but in a wide width, and it fit perfect!  I usually don't need to buy wide widths, but I'm sure glad I did with this one. If you have a narrow foot, a regular width would be great I'd think. I got the black leather and it can definitely be dressed up or down. I like it so much that now I'm considering getting a pair in the grey houndstooth if it becomes available in my size!
