Started wearing the Shape Ups a bit more than 2 weeks ago.  I'm flat footed and have always found walking any distance or standing in one place painful.  I'm speed-walking 4 miles a day in my Shape Ups with no pain whatsoever.  Already notice improvement in abs, legs, etc.  They're everything they're advertised to be and more.  They look great too!  I'm recomending them to all family and friends.  Wish there was price conpetition.  Would prefer paying less than the standard $110 or so for a pair.  Lower prices will come in time.
