These Dash ankle-strap sandals run just the right size. They are good looking wedges that I have worn with suits and dresses looking just fine. They are comfortable and protect my back (posture) and feet, don't know about this losing weight or toning thing, I am just the same (but haven't been on a diet either). They are comfortable for being on my feet but not as much as are the Sleek Fit Mary Janes, the soles seem to not be as thick, but maybe this is just my perception. Great sandals!
