I bought them for running. For nipples, anyone who runs understands, they bleed, it is very painful.
Very good, they don't come off.
The big test was the Athens Marathon. I had put them on from the beginning, and I had several more with me. I thought they would come off. Nothing, with what I put on at the beginning, I finished. Very durable.
