Never underestimate the importance of proper footwork in the golf swing. Sam Snead understood it so well that he used to practice in his bare feet. Perhaps no other golfer has swung with ore power while maintaining exceptional balance. I've discovered that the foundation for a powerful swing is in the feet. They key to proper footwork is weight distribution throughout the swing.
Goof golfers play within their feet.
In other words, their weight is on the inside of the back foot on the backswing and on the inside of the forward foot on the through -swing. The result is a loss of balance, control and power. At address, I toe out my left foot a little so on the through-swing I can rotate my hips with no restriction. My right foot is squarer to the ball-target line to help restrict my hip turn and maintain my knee position on the backswing. I like to keep my left foot on the ground as my body rotates away from the ball on my backswing.
