I really can't imagine these things doing anything, yet I've got some nagging fixation on these. I become enthralled whenever a commercial for some foot pad comes on.Share with me whatever you might know about these things.
Scam. Now go follow your image's advice.
Ask yourself this: Do you really think a piece of cotton with "teh MYSTICAL" herbs will really draw heavy metals collected from all over your entire body out through the feet?
also, there are minerals, etc. in your sweat. that's why the pad changes color. that's why you put it on your feet. feet are sweaty.
