"These were really comfortable right out of the box. Like other reviewers, I was a little worried about the elastic on the top, but I didn't notice it at all once I put them on. (It did leave a slight mark on the top of my foot but I think it will stretch slightly.) The wedge gives them more support than a traditional flat and is super comfy. I'm always a 7.5 and these were true to size. The red color is slightly off from the color on the website--it has more burgundy or maroon to it--but I still like how it looks. I think I'll buy more in other colors!"
