I didn't order these walking shoes primarily for "shaping up," but because I had read that they were also good for posture and could help with foot pain.  In this regard, they surpassed my expectations.  I have some foot deformity from arthritis that has created extremely high arches, as well as have arthritis in the knee, hip and back.  These shoes are not only one of the few that fit my feet comfortably, they also help with my knee pain and considerably relieve the hip and back pain I get when standing or walking distances.  They also definitely do assist in maintaining a better posture, and though it was only a secondary consideration, I can feel that they work out the calf muscles even when walking shorter distances.  The stone/brown shoe is attractive and much more fashionable-looking than the average sneaker too.
The only negative I found with the shoe, and the reason I give four stars instead of five, is that I discovered these are not shoes to be worn in bad weather.  Perhaps due to the very sole design that makes them so great at relieving foot and back pain, they don't seem to shed water properly from the sole and so become very slippery on tile or smooth flooring when wet.
Overall though, a great pair of shoes I'd highly recommend for anyone with foot, knee, hip or back pain or with high arches and well worth the price.
