This is mostly a comfy shoe. It's got good support for the back, but the fit is slightly tight. I tried the wide version (size 6) but it was too big. I think the Medium would be better if you're willing to wear the shoe until it stretches a bit. Overall it looks great and feels pretty good. My feet did get tired when the shoe was new but no blisters.

The white one is a great substitute for a tennis shoe and provides good walking support. There's a slip on style that has a slightly better fit, not as narrow at the upper foot area.
