A player shall position one foot near the outer edge of the free-throw lane line. The other foot may be positioned anywhere within the designated 36-inch lane space until the ball has been released.

Players in marked lane spaces will be able to move into the lane when the ball is released by the free-throw shooter beginning with the 2014-15 high school basketball season. Previously, players could not release until the ball touched the ring or backboard or until the free throw ended.

For those without a scorecard:

1970-71: Hit.
1981: Release.
1993: Hit.
1996-97: Release.
1997-98: Hit.
2014-15: Release.
