I'm 4E but could only get 3E and took a chance. Seems fine. Comfortable but not very comfortable as some say. Maybe because its narrow for me?? Like the looks. A bit warm, worried about summer wearing.  Maybe 3 stars but I'm going to give it a week.

Well it stretched. Comfortable.

4 stars because the heal collapses and you have to put this on holding and tugging the heal. Those of you with big bellies should stay away. lol
