My feet were grim. The soles covered in thick hard skin that was painful and all the above products did nothing for. They sometimes ripped my tights it was that bad! Someone on another forum recommended this. It came last week and is AMAZING, it grated off all the skin on my feet and they are once again soft, smooth and I'm not ashamed to wear sandals! The pile of skin it grates off is impressive too. I don't often recommend things but if you suffer with foot issues then this is a must have product. (I promise I don't work for them!)
