I purchased these shoes in my normal shoe size and when I tried them on they were too small/tight. I needed a half size bigger (as someone else stated in their review). I wish I had known that before purchasing them, but I sent them back and am ordering a half size larger this time. These shoes are so light-weight and well cushioned.
I am not at all a shoe person and prefer being barefoot, but these I could wear around the house all day and not even mind. :) I can't wait to get the new pair and break them in!
