I've had these shoe a week and I really find them to be comfortable and effective. They were a little snug around my toes in 8.5, my usual size, but the nines were perfect right out of the box, no break-in needed.  I also have a pair of MBTs (Raha) and let's face it, they look like hideous moon shoes. They seem to tone my legs more than the Reeboks, but I hate to wear them out of the house!  I've seen some newer styles that look a little better, but the price is a deterrent.  I'm happy with the Reebok walking shoe - just the price, style, and amount of toning I was looking for.
