I wear 7.5-8 depending on manufacturer, I got an 8 for these and they fit length perfectly. They are wide which felt a little odd at first, but they're plenty comfortable for walking around the community pool and using the showers. I docked a star because I ordered a medium width but received wide, at least according to what's on the shoe. For the manufacturer/sellers: If wide is the only option then please make it known. I'm keeping mine but others may have very narrow feet or other reasons why wide shoes wouldn't work and would appreciate knowing before they purchase.
