Why do they make me angry? Not necessarily because there is anything wrong with them, but because of all the promises they make about the health gains you can get from them. they have claimed to cure cellulite; they claim to tone up the butt; and that they can give you an extra workout. The evidence does not support that and as a consequence they are all now getting sued and settling or multi-million dollar amounts. The toning shoes do have a place. The rocker nature of the shoes means they are useful in patients with hallux rigidus, and for that reason, they make me less angry!
