These do run big, so I ordered a but smaller. Normally I am an 8 for flats so that's what I went with. They are still a bit on the big side, but not so much that they are not wearable. Just a little annoying. I don't know that a smaller size would be ideal because they may be too small then.
Other than size, for $20 these are great. They are decent quality, a low heel to give a nice, professional lift and the nude color flatters anything I wear. The toe is nicely rounded, which is a major thing for me because I cannot stand pointy toed heels. I am satisfied with this product and may even purchase other colors.
