When you set up to the golf ball the distance you are from the golf ball at address would be one of those reasons why you have a tendency to hit it on the toe. If I stand too far from the golf ball I bring the toe into play. If I stand to close to the golf ball I bring the heel into play.

Those reasons will help you when you are on the golf course and you tend to hit a shot on the toe or on the heel to make a self correction as you play. Keep those tips in mind and you will hit the ball in the center of the clubface more often.
