Summer = sandals, but wearing them can take its toll on your feet. The Ped Egg foot file is different from your average foot exfoliator in that you can use it when your feet are dry and it doesn't disturbingly resemble your cheese grater.
I was skeptical, but this really does work well. The key is to use the smoothing "emery board" surface on the bottom of the egg after using the metal surface.
Read about this on Consumer Reports and they gave it a really good review saying that it effectively removes calluses and smoothens skin. More effective than pumice stones.
So the commercial sucks. The product dosn't. I use mine right after I get out of the shower between pedicures. Even my husband uses it. :) Highly reccomend
