These pads are a scam
My friend gave me these to try as a gift. She bought them from online ads. These pads are a scam. I told her, there is absolutely no scientific evidence that anything "pulls toxins" out through the feet. The brown colour on the pads, I had it analysed, is just a chemical reaction of the products on the pad as they come into contact with sweat and oxygen - it has nothing to do with pulling toxins out of your body. Your body detoxes itself via the liver and lymphatic system, not via the feet. These pads do not detox your body, they are a scam. Just like those Chinese ionic foot baths, those are also a known scam. Keep your money.
