Honestly, I planned to return these; they were an impulse buy because the price was low for a brief moment. I'm glad I kept them. Initially I had some issue with adjusting the buckle to find the right comfort spot. On one setting the shoe was loose and floppy on my foot, but on the next one it was a bit snug and I worried about the elastic stretching as others have shown in pictures and comments. Finally went with the slightly snug setting and that was the right choice. I work in a school and spend a lot of time walking around. As the day progressed the shoes loosened and were perfectly comfortable all day long.
