Step and Slide. The step and slide is used primarily to bridge the gap (close the range) although it is not normally used with an attack. However, it is effective in gauging and obtaining correct range from which to launch an attack. In the step and slide, the lead foot steps forward about 6 inches and the rear foot slides up to where the lead foot was at.
Push Step. The push step is used for bridging the gap combined with an attack. The step is works well with a punching attack. In the push step, lift the lead leg, push off with the rear foot, and lunge forward with the lead leg.
Shuffle Step. The shuffle step is more like a pulling movement than a stepping movement and it is quick since it has only one movement to it, unlike the previous two steps. The lead foot stays flat but with just light weight on the toes and ball of foot. As you move, the rear leg pushes off, the lead toes dig in and pull forward, and both feet shuffle forward. If is a subtle, deceptive motion but it is powerful when the body mass is instantly thrown in behind the attack.
