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.

Kim Clijsters announced her decision to retire from professional tennis for a final time. She attempted a comeback in the middle of a global pandemic and struggled to find her game. She played five tournaments and lost in the first round in each of them.

The retirement will allow Kim Clijsters, who now lives in New Jersey, to focus on her family. She drives her three kids to school, helps with homework, and cooks for the family.

Speaking of her decision, Clijsters said:

Yeah, it’s been on my mind for a whileI still love to hit the ball. With my schedule three, four days was enough to keep my rhythm under control but definitely not good enough if I decided to play another tournament. Say, if I picked Australia, it’s three, four weeks. That’s just not possible at this stage in our family life.

Clijsters won six grand slams – four in singles and two in doubles. She was ranked number 1 in singles and doubles – including holding the number one ranking in both simultaneously. In 2017, she was International Tennis Hall of Fame.
