It's one of the hottest spa treatments around. A foot bath that some spas claim can actually remove toxins from your body right through your feet. Spas charge up to $85 for a foot detox that supposedly draws toxins into a tub of water that changes color. But Dr. Stephen Barrett, M.D. told INSIDE EDITION that the device cannot possibly draw toxins through the feet. We bought our own foot bath unit and had it tested by an electrical engineer. #InsideEdition
