The most effective way to prevent black toenails is to run in shoes that fit properly. You should have a thumbnails width room between your big toe and the front of your shoe while standing, not sitting. You should also wear moisture thin, moisture wicking socks to prevent increased heat build-up.
If you increase your distance regularly and very gradually, your toes will adjust to each new maximum distance and only complain when you extend farther. In a marathon training program, almost everyone gets at least one black toenail. Running faster than you should be running, at any time during a long run, will increase the chance of this injury. Hot weather also improves your odds of getting one. When itâs warm, your feet swell more than they would on cold days.
