I have never wore black toenail polish before and I don't plan on wearing it anytime soon just for the record. Another thing I have never had before was black toenails from running. I have run a marathon, multiple half marathons, and many other small races and I don't ever recall having a black toenail or losing one. I did come close at one time with a toenail that looked a little off but it eventually grew out, but never fell off.
