Hello, I used the foot detox pads on and off several years ago. I didn't feel any difference and as an experiment put some on parts of my body that don't sweat so much and they were dry in the morning without the dark brown discoloration. Tried putting some tap water on a pad and it caused it to turn the dark brown color.
Found them to be more trouble than its worth since that dark brown sticky stuff as well as the tape would leave a sticky residue on my feet that required major scrubbing to try to remove. If I didn't get it all off, fuzz from my socks and dirt from the floor would stick to my feet.
