They are pads that you stick to the bottom of your feet, a bit like a giant plaster, and they are supposed to draw toxins out of your body. There are various different brands of detox foot pads available, and I imagine they all work in the same way.
The pads are placed on the feet because that is where the ends of several meridians are, apparently. For this reason, it is supposed to be a good place to draw out toxins from.
You are supposed to wear the pads for 8 – 12 hours, so it is best to leave them on overnight as you sleep. They start as grey/white in colour. When you take them off in the morning, they are supposed to have turned a dark colour. I found several photos people had taken of the pads after they removed them, and they are covered in greenish brown gunk! I read in some places that if you use the pads for several days in a row, they will eventually stay light coloured because they will have drawn out all the toxins.
The first night I used the pads, I got really hot! Usually I feel the cold, and sometimes even wear a jumper in bed. However, I couldn’t get to sleep because I was so boiling, which is very unusual for me. I don’t think my room was any hotter than usual. In the morning, I removed the pads, and they were indeed dark coloured and gungy, as I expected. The second night, my temperature was normal and the temperature thing never happened again. It could well have been a coincidence, and nothing to do with the pads! For the first few nights, I didn’t sleep very well or I took a while to get to sleep. That could have just been because I wasn’t used to the sensation of having something stuck to my feet. After the first few, my nights were pretty much normal.
The pads were not very comfortable to wear. Sometimes they dug into my feet if I stuck them so that the edge of the pocket containing the ingredients was in a particular position on my foot. It could feel a bit sharp. Also, it gave a feeling of pulling my skin when I moved my feet around. This was similar to the feeling you get when you wear a plaster on a part of the body that moves.
Since using the pads ive noticed that im not as tired as i normally am, im feeling healthier, there is no evidence to prove they work but im really happy with them and ive just ordered more.
