Works better than a pumice stone and it more sanitary
I had been using some man-made pumice stone thing for years, but it was getting gross and I tossed it.  I got this foot rasp instead.  I only use the smoother side for my heels.  During the summer my heels get dirty and dry from walking around the house with no shoes.  I keep this rasp in the shower.  I rub a bar of soap across it and then smooth/clean my heals.  It works very well and doesn't rub the skin raw like a pumice stone does.  There are no little nooks and crannies for mold to breed like with a holey pumice stone.  It can also be sterilized.  I wish I had discovered this years ago.
