Tennis is a beautiful game. But have you seen a tennis player’s feet without their shoes and socks? It’s a horrible sight. The feet take a beating with the insane amount of running the tennis players have to do. British tennis star Emma Raducanu once confessed that she had no toenails.

Tennis players have to deal with blisters, falling toenails and in general ugly looking feet. Sometimes during matches, players remove their shoes and socks to get their ankles wrapped or to attend to an injury. TV cameras quietly zoom away from the player’s feet to show you replays of previous points or the spectators.

But it’s not just tennis players. Marathon runners and ballet dancers have bad feet too. They miss toenails or in some cases , the whole foot may be deformed.
