The four components of Quick Feet include:

1. The timing of the footwork - When the pitch location allows, start to shift the body around the ball to get a head start on the footwork.
2. The length of the step - The step should be as short as allowed by the batter location, pitch location and the catchers set up location (near or far away from the batter).
3. The direction of the step - The direction of the step (Jab Step, Tap Step, Replace Step) is also dictated by the location of the batter, pitch and set up. 
4. The strength & quickness of the lower body.
