My poor feet. I wore these for one day and I got grooves in the tops of my feet and it actually cut the blood flow off! I'm normally a 7.5, but after reading other reviews saying they can run big, I went with a 7. I tried to return them for a larger size and Amazon refused. Such a shame. These shoes are SOOO cute and were perfect for me to wear with damn near anything. I will try a size 8 at some point.
