works as promised but the no mess socks are too small [SEP] i purchased this for my daughter who had thick cracked caluses on her heels she used it and for the first couple days she did not think it had worked much then last night after her shower she called me into the bathroom to show me the skin that was literally sloughing off her heels kind of gross actually but her feet are looking so much nicer now the only issue she had is that the plastic no mess socks that come with the kit were too small for her size feet she had to squish her feet into them which left very little room to move her feet inside to work the gel around which is what the directions say you should do if you wear anything larger than about a womens size you might want to think twice before ordering this despite this glitch i am still giving the product stars because it does work very well
