OK, this may sound like a wizards/witches cure but it has worked.
The human foot has the most sweat glands then any other part of the body, all the junk in your body tends to wind up in your feet, they make a "Foot Detox" pad that will literally suck all this junk out of the feet, you try it what do you have to loose.
Here is some info on this, you can also google about it.

And a good place to get some pads.

I didn't think this stuff would work as I had a job that required me to stand for long hours at a time, and some days my feet killed me at the end of the day, a friend recommended these pads that you put on your feet, he said try it out, the first time I did one treatment I almost threw up when I looked at the pads, when I took them off my feet they were black and smelled like coal tar.
After several treatments they cleared up and my feet had never felt better, but now with my back injury I can't feel my feet so I don't use them any more.
