Defend Yourself With Footwork

In looking at defense what is the best way to defend yoursef? Footwork. Good footwork puts you in position to attack and gets you out of position of being attacked. You want to be in position where you are just out of your opponent's range but close enough where you can launch your attacks and get back to a safe distance.
