Ideal Angles for Straight Shots
The correct toe position at hip height is tilted slightly toward the target line, so that the club's leading edge matches your spine angle (left). That's square. From there you can achieve a square face at the top, parallel to your left forearm, setting up square impact.
Practice swinging back to hip height without any hand or arm rotation. Here's a swing thought: Keep the logo on your glove pointing out. If the logo points up, you've spun the face open.
