I normally wear a 7.5 but ordered an 8 and I'm glad I did. I wore them outside for the first time and they were very comfortable, with good support. They are very easy to put on. There is room for a thin sock but definitely not a heavier pair. There were none of those squishy sounds some other shoes make when you walk- in fact my footsteps were silent! I got them in black, which isn't very summery, but they look good. I would recommend them.
