In 2011 I uploaded a video to my YouTube Channel showing the footwork of a lot of famous golfers from throughout the years.
That video attracted a lot of attention as I zoomed into the feet of these players (including myself) and showed a very different
activity in the footwork than what most people noticed or modern instruction had distinguished should occur in the golf swing.
The close up of the feet allowed the viewer to see a very distinct rear foot drag in all the swings. This grip and grind in the feet
whilst not a goal in the golf swing is definitely a vapour trail of wonderful ground pressures into the feet as a balance and support
system to help move the club void of stalling the body or over using the hands.
