I was nervous about ordering these shoes because of the negative reviews. I normally wear a size 8.5-9M. I do have slightly wide feet, so SOME shoes that are too narrow will hurt. I've never bought wide shoes, though, so I ordered the 9M shoes here too. They fit PERFECTLY. I'm not sure why other reviewers had issues, but they fit me fine and are super comfortable. They are great for what I wanted them for (travel), and I can walk around with them all day and not be in pain. The only thing that bothered me is that there was a weird smell to the shoes when I got them...they ARE synthetic leather, so I'm guessing the smell was chemicals. I sprayed them with shoe spray aired them out and now they're fine. I do recommend these shoes in a M size, I can't attest to the wide/narrow sizes. Just don't order a size up.
