These are the most comfortable shoes I've ever owned.  I didn't buy them because of the "shape-up" qualities, although heaven knows I can use shaping up.  I actually chose them on the advice of an orthopedic surgeon who was treating me for a stress fracture in my foot.  He suggested that they might also be beneficial for other foot problems I've got, and he was right.  I have a pair of regular Shape-up sneakers, and they're comfortable, too, but I prefer these for work -- they're a little dressier.

I wish I could afford a pair in every color -- I just love them!
