Hi.  Another question, please.  ☺️

Are turns/pivots and spins/pirouettes supposed to be on the ball of the foot, or (almost) the whole foot?  I have watched the pivot and pirouette videos, and it is taught that most of the weight should be on the ball (and three inside toes).  But it appears like most of the foot is flat, and I have heard Brian say you should think about the depth of a sheet of paper between heel and floor.  Yet I have often seen pros completely lift the heel.

By the way, I don’t know if there is a right or wrong way to do this, but I teach myself the footwork (of several patterns) first, till I have them down, then go back to learn the arm & hand movements.
