Very interesting thread. I'm going to purchase the coated ones from Amazon and give this a try. In reading the thread though, I'm uncertain about placement. I have a very deep aching in all of my toes. Do I just tape them to my toes? One in the middle of each set of toes? I read something about placing them on the ankle for toe pain...? I also see it likely won't help the burning on the bottoms of my feet, but is there any harm in using one on the toes and one on the bottom of the foot at the same time?
