I'm sure you're all familiar with this:
One oftens hears that there are "frame" judges and there are "feet" judges; judges that look up, judges that look down; top or bottom judges, you might say.
Big picture, little picture, I say.
Your frame and posture is evident before you walk on the floor. Your footwork shows me how you move on the floor.
Footwork is a symptom. It's an indicator of leg swing, rise and fall, control of movement, proper use of your joints, flexibility, and interest in DETAILS. As I'm looking at your feet, I'm really measuring how much you learned (and retained) from your education.
As usual, there's a scale on which you can perform footwork:
If you're starting your journey of ballroom dancing, you need to know what part of your foot to use when. Like, verbatim. Doing the proper footwork will help you do other techniques correctly. Once you "get good", footwork just happens. But until then:
knowledge + practice = footwork
