I ordered a 9.5 as I usually wear it with other brands. I had to return them on a size 9 because the 9.5 felt like they almost fell off my feet while walking. These are loose shoes, especially since you cannot tighten or tie the laces. The laces are elastic and cannot be removed or adjusted (unless you wish to cut them). I'm surprised other reviews say these shoes are too tight or too tight. They are spacious. Don't buy these if you're looking for shoes that can be tightened. I wish the seller had made it clear that these shoes cannot be tied/tightened.
