I got these for Christmas, and like other reviewers, was very skeptical. I know they look like corrective shoes so I was a bit embarassed to wear them at first. Four months later, I gave them a chance. They motivated me to walk in the mornings and I love the rolling action for a smooth walk. (I like to run but these aren't really for that, just an FYI.)
I have disgustingly flat feet and many times, shoes really hurt them. These, however, do not. They are actually quite comfortable. I don't really find them to be any heavier than other shoes.
I tried on the Reebok EasyTones at the mall and they seemed awkward and very stiff in comparison.
I avidly workout, and have not worn these long enough to tell if they are firming or not, and since I do weights I have not been sore yet.
When these wear out, I will definately be buying another pair.
