The setup is a basic foot bath, with a plain tub filled with warm water. The twist? An ionizing machine sends out a low-voltage electric current to charge the atoms in water molecules. It's said that these charged atoms attract and neutralize negative toxins in your body. Basically, the impurities gumming up your system get pulled through your feet as if drawn out by a magnet.

Not only does a foot detox soak help to cleanse and disinfect the feet, but it also stimulates blood circulation to reduce swelling and relieve minor aches and pains. Increased blood circulation supports the health and wellness of your entire body and can prevent various health problems made worse by poor circulation.e.
