Was scared about buying these I really wanted a shoe that would cover more of my ankle but these do fit nice. I wear a 8.5 and while there may be wiggle room that is okay. I do have one small complaint and that is that  I wish I could tug on the tongue to pull it up,but I can get pass that .Wore them all night and they were mostly comfortable. I mean there is a piece on the top inside left foot that was rubbing into my foot and agitating it a little but nothing that would keep me from wearing them. I could put a orthic in it however it would make the toe area very tight and to uncomfortable.
