Review title is Not So E-Z [SEP] My mom and I both received these as gifts.  It does not stay put and can actually throw you off balance when it goes sliding.  The actual product for both of ours is also different from the pic on the box.  Ours both have very long, firm bristles top and bottom that are difficult to move back and forth through, and there are bristles completely surrounding the pumice stone so that you can't really get to it.  The pic on the box and the advertisements show no bristles at the back of the "shoe" behind the pumice stone, only in front of it, so that it's actually accessible.  The way these are made, the stone might as well not be there, because you can't use it. I'm not even sure it's an actual pumice stone after running my fingers over it--it feels artificial and has a different texture than pumice.  It's a good concept, and will at least take off surface dirt--if you can hang on to it.  I actually worry about it causing seniors to fall, instead of preventing it. I have to think there are different models; I looked online at the commercial and the plastic looks different and there are several colors, plus no bristles at the back.  It says EZ Feet on the box, but it looks like this may be a cheaper model than the one they push on their site and their commercials.
