I was a bit skeptical in the beginning but I did notice a slight difference the following day. There was a reduction in the soreness I experience. I am on my feet a lot at work so I thought I would give these a try. They arrived quickly, were nicely packaged and were not messy. They were wet and darker when I pulled them off the next morning. I can't speak to what they actually removed from my soles but I did feel refreshed the next few days
