When did it become legal to use your feet in volleyball?

In volleyball, using your feet to play the ball became legal with the introduction of the official rules by the Fédération Internationale de Volleyball (FIVB) in 1964. Prior to that, players were not allowed to use their feet to touch the ball. This rule change allowed for more dynamic play and creativity in the game. Today, players can use any part of their body, including their feet, to play the ball as long as they adhere to the other rules of the game.
