This is my third pair of MBT's. I bought these at the recommendation of several neruospinal surgeons I worked with. I spend as much as 12 hours a day on my feet, many of them standing stationary. My back was killing me, these shoes helped stop that. I also had a co-worker with a knee problem from an old injury, she bought a pair and no longer needed cortisone injections to be able to work. I tried the sketchers "shape ups" and they didn't compare. Of course the reason I bought these shoes was not for the "shape up" capabilities although those were also present. The reason I'm giving these shoes 4 out of 5 is unlike my last pair this style is made for someone with wider feet and don't fit as well as my last pair. Also be aware to order a 1/2 size up from your usual size. I also made the mistake and ordered a pair on e-bay and they were a China knock off. At least here at amazon you get what you pay for.
