Just stumbled across this sorry if it's old and no one cares to check it...
The foot position Hogan used, as I've found, is really more appropriately described as a "closed to the body" stance with every club, just adjusted as the clubs get longer. And, yes, I mean this even when the stance is open. Just keep reading it'll make sense... kind of.
If you watch in his pre shot routines, he starts with the feet close together, parallel to each other, but at about a 45ish degree slant to the left of the desired stance (in the case of wedges, slightly open... etc.). You'll see, if you stand closer or "hugged up" to the ball, as I like to say, as he did in his pre shot, you can do this while keeping the toes on the same line your actual stance will be on. From there, move the left foot out and back from the target line, maintaining the angle of that foot, then, move the right foot back and out slightly. At this point, the right toes are pointed inward. Now, this is important. DON'T FLARE THE RIGHT TOES OUT, but instead, pull the right heel inward. This will allow you to maintain the leg/knee position, with the knee inward. It ultimately feels like the leg is twisted inward, which is awesome because it makes you JUST uncomfortable enough that you want to release the leg, and when you do, VOILA the rest follows perfectly with basically no effort. Unless you decide to interrupt. I recommend not interrupting. If you set up right, the first move is done for you.
You'll see that the toes end up on a line parallel to the one they were on when you had your feet close together, but now they're both pointing outward. So, as long as you adjust the RIGHT HEAL to cause the toes flare out to the right, and keep the left foot the same, it'll give you the feeling of lining up with a fairly drastic closed stance, but everything will be as it should be relative to the target line. The knees and the posture allow you to feel the power that we feel when lining up for a draw, while conveniently having your shoulders, hips, and "feet" on the actual target line.. Done properly, all of a sudden that ball position he claimed to be off his left heel suspiciously looks and feels A LOT more like it's off the right heal, at least relative to where you are holding your "pent up energy" or "load". No one else will know if they're watching, but you will absolutely feel it if you do it right.
It's kind of a mind f**k, trust me I know...I'm the one who had to figure it out... but try it. The key is doing this little pre shot gimick, and keeping the body/knees in the orientation they are in when your feet are close together and parallel to each other, and your body is hunkered down... what I call the "mini hook stance". That's how he did it, I'm 100% convinced. Because, well... you can watch him do it in any video of him getting ready to hit a shot. Tough to argue that logic.. (In summary, line up with your feet together in a ultra narrow hook stance toes pointed 45 degrees left, then just adjust the feet back and out, keeping the toes on a line parallel to the one they start on. Do this WITHOUT changing the angle of the left foot, but by pulling the right heel inward so that, visually, the right toes are flared out, but the right knee/leg orientation remains the same as when the toes are pointed in).
Ya, it's a mouth full. Sue me.
After all, his problem, as he said, was he had such a bad book he couldn't aim far enough right to play a dog leg left to right or he'd hit the trees. When you do this correctly, you'll see it's basically like aiming out to the left 45 degrees like you're going to hit a hook 45 degrees left of THAT (90 degrees left of your target), then, keeping everything the same, just shuffling your feet back to the actual target. Like I said, it's a mind ****, which in my opinion is the very reason no one ever figured it out.. but you'll see how everything ends up working out. Just mess with it, trust me. Did wonders for me. And I was a hooker, a bad one. No, not like Red Light District shit. Worse.
Oh and Hogan said "Reverse every natural instinct you have and do the opposite of what you're inclined to do, and you'll probably be close to having the perfect golf swing."
