A side to side kick move is a Charleston variation that derives from the solo jazz world. It is more commonly seen in lindyhop as a hand to hand Charleston, danced in partners, but here is the footwork done as a solo move.
As a breakdown you need put kick your right foot on the diagonal to the right corner then change direction and switch your feet to face the opposite corner. Place your right foot on the ground and switch it with your left then kick to the left corner.
The key to this step is keeping your weight over the body, feet flexed at all times and a light bounce throughout the movement.
To make the movement seem larger, create large circles with your arms to lift the upper body and fill the space. This makes the step more eye catching and fills the space.
