I've got feet like a hobbit with cracker soles so hard I can literally shave off layers with a knife-yeah, skeeves out my wife. So, I thought I'd give this stuff a try.
After a couple of weeks my feet do seem less crag like. Not exactly soft and smooth but certainly better than they were BUT this stuff stains clothing. socks you handle as you pull them on over your treated feet, a pair of suede desert boots became discolored why my thumb touched them before I could wipe the excess goop off my hand.
Unless you wear only tube socks or are willing to walk around on the balls of your feet after applying the goo but before you touch garments, so you can wash your hands off, this is a mess. and I'm not sure worth the bother.
