Tennis Shoe

Tell me, why is it I couldn’t just wear my running shoes on the court?

Well it’s performance related, but it’s also a safety issue. Running shoes are made to go straight, in a straight line, they’re not made for lateral moving like you do on a tennis court. They don’t have as much support as a tennis shoe has, so you’re more likely to turn your ankle. And you’re not as low to the ground like a tennis shoe is. So again, you’re more likely to turn an ankle in a running shoe.
