I once had an aerobics instructor who suggested butt toning exercises you could do (unobtrusively, of course) while standing in line at the grocery store or hanging from a strap on the subway or while driving in your car. Great. No more excuses for not being fit. Well, these shoes take that idea one step farther . . . literally. Every step you take in these shoes is a leg-toning movement. And so you will want to wear them wherever and whenever you can. Step out, ladies !
