I won't try to say that I've tried every fitness shoe on the market, but I'm extremely pleased with the Skechers Shape Ups.  It does everything they advertise.  When I first got these shoes--even with the warnings--I thought that I had purchased a new torture device.  Your legs and feet HURT.  However, after about a week or two, my entire legs tightened right up.  These are now the only sports shoes that I wear.  I also want to add that I do encourage buying this from Amazon because of the savings--BUT TRY THE SHOES ON IN A STORE FIRST.  Your size might be different in these shoes, and you do not want to end up stuck paying these kinds of prices for a shoe that doesn't fit.
