These shoes are like walking on air. I am on my feet 8 or more hours each day, and these shoes are as comfortable as the sneakers, but look more dressy and can be worn with dress pants.  Shape-ups help ease the pain of plantar facitis that I suffer from daily inbetween the cortisteroid shots I get to help with the pain.  Because of the different way I walk in the shoes, they help relieve stress on my ruptured discs and as a result, my back hurts less.  I have told many people how wonderful these shoes feel and many of them are wearing them now, including my chiropractor and orthopedic surgeon. I am happy to see them in sandals and other forms. They are worth the money!
