"Compress untill the feet are at an angle of 45 degrees along with the shin. The thigh will automaticly be at the same angle."

No - that is your mistake. Your thigh should remain relatively vertical as the knee bends. This is what ballroomlady seems to have just disovered - how to do it, and how much it helps.

"Even when the heel touches the floor the body stays verticle and is over the REAR of the supposed feet."

But after the heel touches the floor, as the knee bends, the body moves forward to stay vertically aligned over the advancing knee. It does not stay balanced over the foot, it advanced beyond the foot.

This is, after all the very same position that has been prominently on display in picture two of the forward walk for the entire duration of our argument... knee forward of the foot, body aligned over the knee, well forward of the foot and thus OFF BALANCE.
