Yes. Both feet must be touching or entirely outside the line. A throw-in is incorrectly performed if one (or both) feet entirely enter the field of play at the moment of release. Note that there are other requirements for a correctly performed throw-in, but this is the only requirement for the feet.
To properly execute a throw-in in soccer, stand with both feet on the ground behind the sideline, hold the ball with both hands, extend your arms behind your head, and throw the ball over your head with both hands while keeping both feet on the ground. The ball must be thrown from behind and over the head, and both feet must remain on the ground until the ball is released.
In a throw in both feet need to stay on the ground. You may get a running start and drag one foot behind you, but both feet need to stay on the ground. If a foot is lifted the throw in will go to the other team.
In soccer, when performing a throw-in, at least part of both feet must remain on the ground. The player must not lift their feet off the ground during the throw, which is to ensure stability and proper technique. Additionally, the throw must be executed with both hands, and the ball must come from behind the head. Failure to adhere to these rules can result in a turnover of possession.

The Oche, or throw line, in darts is the designated area from which players throw their darts at the board. It is typically marked on the floor, and players must stand behind this line when taking their shots. The toe line refers specifically to the front edge of the Oche, where players must position their feet; stepping beyond this line while throwing can result in a foul, and the throw may not count.
The free throw line is 15 feet from the basket in both NCAA and NBA.
