A Summer Of “Low Impact Heel” Investigation Now Bears Fruit

I mentioned in an earlier posting that I had made several new discoveries in the subtleties within the standard model of the MCS Golf Swing.

I suppose the early days seemed so much more fruitful than the past couple of years have been, due to the diminishing number of things to investigate and clarify.

I’ve spent this entire season looking into the nature of a low trailing heel impact, and only in the past week or so, I’ve made big strides in the clarification process.

First, I have actually discovered additional “speed brake” issues with my own swing, because of having incorrectly applied the sequences that I will discuss below.

Meaning, however fast I’m able to swing now and however far I’m able to send the ball, I’m still not utilizing 100% of my capacity.

Close, But Not There


Second, there seems to be, as always, a degree of “yes and no” when it comes to anything regarding the swing, and the low trailing heel impact is another one.

The reason is that there are infinite variations of how someone may swing the club using the same model, and when it comes to the trailing heel position at impact, I have found several positions that do not make the swing good or bad, but simply follow what has occurred to that point:

  • There is a swing pivot (and also a setup position) that will produce a low leading heel on the back swing pivot, and this will reciprocate in a low to flat trailing heel at impact,
  • There is a swing pivot (and also a setup position) that will produce a higher leading heel lift, and this will again reciprocate the down swing impact position with a high trailing heel impact,
  • Taking the second pivot mentioned, you can also exchange the high heel at impact with a lower heel but which requires a “short stop slide” at and through impact

Greg Norman’s “Slide”


That’s what I’ve got so far, and the reason I want to clarify all of this is because everyone will swing in a slightly to extremely different manner even within the standard MCS swing model, so this will help many people who are struggling with one aspect of the swing or another.

Mike Dunaway’s Step-Around


I’ve also, in this process, been able to solve the riddle of how Mike Austin and Mike Dunaway claimed to swing the same way where Austin had a high leading lift to Dunaway’s lower (sometimes almost nonexistent) leading heel lift, with Austin’s heel at impact also being either higher than Dunaway’s or being accompanied by a slide at impact, compared to Dunaway’s step-around.


Believe it or not, they did swing nearly exactly the same way, but there was a variance – meaning, they used the same model slightly differently, which produced the different looks between the two.

Not only that, sometimes, Dunaway stepped around, sometimes he had the slide:


I’m just trying to wrap all of this up before the outdoor season ends so I can give definitive answers with video to back up what I’ve done with the work this season.

Shouldn’t be too much longer!

    I know we’ve discussed it before, but that trail foot looks almost completely square to me. My feet are flared a good 45-50 degrees, your trail foot looks like 10. Another thing to note is the lead foot, as it’s flared, but replants in a more flared position coming down. Anything there to note?

    I have a flat heel impact, and I can say for certain that if my trail foot wasn’t flared, I’d naturally come off the heel prematurely. With my feet being flared as much as I do, it’s actually very difficult if not impossible to jump off that foot.

    Just what I see, but I’ll let you think on it.

      I took a look and while I don’t see that, MMJ, it could be something to do with the nature of the pivot and re-plant for the down swing. Jack Nicklaus for one example had a more square leading foot at the setup than on the down swing, so he was re-planting more flared.

      It is certainly nothing I do consciously, and would seem to be a natural action. I hope that helps 🙂
