Point one foot inward and the other foot forward. Your feet should make a "T" shape. Twist the inward foot and point it outside and then twist it back again. Make sure your shuffle foot stays on the ground to create the sliding effect.
Slightly lift your other leg up when your first foot twists inward, and put your leg down when the foot twists outward. Move slowly until you get the coordination of this part down. There are instructional videos below to give you a visual of the dance.
Listen to the rhythm of the music to help your body flow with the music. Pay attention from other shufflers, and don't be afraid to experiment and borrow some of their moves. Add some flair to your shuffle by adding kicks and turns. Learn the timing and placement of your special moves to add flair to your shuffle.
