I have Rheumatoid Arthritis (which effects every joint in the body), my feet being the worst.  This will be my second pair of these.  Once I started wearing them with this type of sole, now if I put on any other shoe, my feet swell.  This shoe is the most comfortable shoe I've ever worn.  I can't say anything about the "shape up" part, i think that was just a marketing ploy.  But I can never say enough about how much better my feet are now, and my hip pain stopped (RA again), and back pain stopped.  They are worth every penny to me.  And i hope Skechers never stops making this sole.  I wish I had 4 hands so I could give it more thumbs up, instead of just 5.

29 April 2013 Update to Review -

This second pair is NOT lasting like the first pair I had.  I have had these since October, and the toes in both shoes are blowing out, and the stitching is coming apart.  The amazon seller says my "window" of return has closed, so I sent an email directly to Sketchers.  For the money they cost, I should get more than 7 months wear.  I wore the other pair for nearly 4 years.
