Interesting Shooey PM in the box for U

For any given last/insole/outsole combination, there is only ONE correct heel height: the one that makes the outsole touch the ground with the treadline at the joints.  From the picture, it looks like your 'modified' heel throws the treadline too far forward, past the joints -- though that could be an artifact of the picture's angle.

That being said, adding a haf sole does necessitate a higher heel than a heel on a single sole on the same last, as the outsole across the correct treadline is thicker, and thus the heel must be raised to keep the treadline at the proper location relative to the ground.  In essence, one needs to add a layer to the heel equivalent to the thickness (at the treadline) of the haf sole.

Another way to check is the toe spring: the toe spring -- the distance of the outsole from the ground at the end of the shoe -- should be the same on all shoes made on the same last, regardless of the thickness of the outsole, be it single, double, or haf.

Depending on how and where one defines 'heel height' -- from the ground to the bottom of the outsole, from the ground to the top of the outsole/bottom of the upper, at the back of the heel, at the front/breast of the heel -- will determine the correct heel height for any last/outsole combination.  However, it is generally NOT correct to say a single sole will require a higher heel than a double sole, even given the definitional uncertainty in using the term heel height.

^ same sole thickness, different heel height.

Sorry, I am a bit skeptical about all this overanalyzing... I think you're the guy who once said that one of my GG bespokes had "crude" sole stitches. Perhaps that explains my skepticism.

What does HAF stand for?  HAlf-to-Full?
