To do the side-to-side step, bend over with your feet together, stomp with your left foot as you lift up your right foot to the side and slap the side of your right boot with your right hand. Stomp your right foot as you lift up your left foot, and slap the side of your boot with your left hand. Do this four times. It should sound like, "stomp-slap, stomp-slap, stomp-slap, stomp-slap."
After stomping and slapping four times, stomp with your right foot then straighten your torso a little, your right foot still up and clap your hands together, then drop your right hand and slap the inside of your right boot near the heel and stomp with your right foot. Lift up your left foot as you stomp with your right, clap, drop your left hand to slap the inside of your left boot near the heel, and stomp with your left foot.
Lift up your right knee and slap it with your right hand, clap your hands and drop your left hand to slap the inside of the boot near your heel. Stomp your right foot, lift your left knee and slap it with your left hand, clap your hands, then slap the inside of your boot near your heel with your left hand and stomp your right foot.
After lifting each knee and slapping the inside of both boots, jump up and clap your hands behind your knees. Land, stomping with both feet, then repeat the jump.
Keep practicing the above steps until you are able to do them at a faster pace. As you become more and more comfortable with the dance, you will be able to add your own variations.
