When an NBA player steps on the court, they want to make sure they have the best possible grip on the floor. To do this, they wipe their feet on a towel before stepping onto the hardwood.
The towel helps to remove any dirt or debris that could be on their shoes, which could potentially interfere with their traction. In addition to wiping their feet, players will also often use the towel to wipe down their arms and legs. This helps them to stay dry and avoid any potential skin irritations that could come from playing in a sweaty uniform.
While it may seem like a small thing, making sure your feet are clean and dry before a game can make a big difference in your performance. So next time you see an NBA player reach for a towel before taking the court, you'll know why!
