Ball change

Ball change is a dance move that consists of two steps: a partial [weight transfer] on the ball of a foot, followed by a step on the other foot.

Kick ball change

Kick ball change is a dance move that consists of a kick followed by the ball change. Normally it uses a split-beat count: 1&2 or 1a2 and has a syncopated feeling, i.e., the accent of the motion is on "two".
The move consists of three distinct actions and can be started with any foot.

"One": A kick or flick with the left foot. After the kick the foot naturally swings back.
"And": Slightly push off the floor by the ball of the left foot behind or by the right foot.
"Two": Step with the right foot.

Details of each of the three actions vary depending on dance and styling preferences.

Heel ball change

Heel ball change is a dance move popular in line dances. On count "1" the heel touches the floor forward. On count "&2" the ball change is done starting with the same foot. The whole move is done in place.
