A solid foundation is key to a balanced and powerful swing. If you are too narrow, balance will be jeopardized. If you are too wide, you will restrict your movement throughout your swing.TOO NARROW
A base that is too narrow does not provide enough stability to support a driver swing. STANCE FOR POWER!
I am slightly wider than shoulder-width for good balance. For your mid-irons, your stance should be slightly narrower; and with your shorter irons even narrower. TOO WIDE!
This is overkill. A stance that is too wide restricts your turn and downswing movement to your finish.
