I had a guy working at my house a few years ago that believed in copper this and thats. He had insoles in his shoes, a back brace and maybe other copper things. He held his arms out and told me to give him a push. He kept his balance. Did it again without the copper insoles and he lost his balance. Then he set the insoles on the floor for me to stand on. Same results as his. Strange. Maybe there's something to it or maybe it was a trick of some sort. I do know coppertox works if you happen to get the footrot. lol
