Witness the greats play the pull shot and you will learn nothing. A good pull shot is played instinctively after careful deliberation and many hours of practice.
Whether played off the front or back foot, your weight must be even, progressing and at once forward-moving and retreating. The central pivot of the pull is the ball and your bat must describe a weak parabola bethwart it.
Make good contact and you will feel marginal and overwrought. This is not to be sniffed at and almost entirely incorrect, so keep practising and remember this memorable and helpful mantra:
“Height over waist, ball bethwart bat. Width beyond knee, bat bethwart legs.”
