Has anybody ever tried this? I found a spa near me that is doing this now and I'm wondering if it's legitimate and worth the money. You soak your feet in an ionizing footbath with positively and negatively charged ions. The ions are supposedly absorbed through the feet into the body where they attach themselves to toxins. Then the toxins are supposed to come back out through the feet into the water. If this is true it sounds like a great practice, but I'm just not sure I believe it.
