After going to a retail store, having my feet measured, and then getting my gait filmed while on a treadmill,  these shoes were the brand and style recommended.  The store didn't have the color I wanted.  I came back and found them on Amazon.  If you don't go through the actual foot measuring process, I'd recommend ordering a size larger than you normally do.  I'm not a big time runner, but walking and exercising in these is a much more pleasurable experience.  Very light weight, but sturdy and supportive.
