Some people seem to be having a lot of confusion about the physics of body weight. Specifically, that there is a difference between what part of the foot is bearing the pressure of the weight, and where the weight is located. Let my illustrate with a simple but informative case.

If you stand normally, feet together, weight located over your heel, your weight is in/on your heel and it is located over your heel.

Now if you send your weight forwards, what happens?

If you send your weight very slowly, your weight might end up located OVER your toe, and also resting ON your toe.

However, if you drive your weight forwards as for a dance action, something different happens. You weight will still go OVER your toe, but the actual pressure will, as long as your maintain the drive, remain further back.

If you stop the weight over your toe and try to stay there, of course you would then have the obligation of maintaining your balance, and so would support your weight from the part of the foot direclty under it, the toe.

But to send your weight, you have to push from a point BEHIND where it is located.

Send your weight to the toe, and as long as your are pushing, the push comes from further back.

PROJECT your to send your body BEYOND your toe, and your weight will be located OVER a spot on the floor in front of your foot. But as long as your keep pushing from the standing foot, your weight will still be located ON your standing foot, because that is where the pressure is coming from.

When you can no longer keep yourself up by pushing from the standing foot, that is when you have to start arriving on the moving foot.

During the entire drive the body weight is located ON the standing foot. But during most of it, the body is not OVER the standing foot - instead, it has projected furether and further beyond.

And yes - when it is beyond, it is NOT BALANCED, yet that is not a problem as long as you support it by maintaining the drive.
