Seems counter-intuitive to do this to a custom skate known for it's "wrap" but after my heel lift issues improved some with skipping the top eyelet (thanks everyone) I decided to mess around with a heat gun.
I noticed that the ankle at the very top of my old supremes was splayed out wide, and I never had heel lift issues (despite having at least the same amount if not more dead space than the trues) So, I decided to open up the "wrap" at the very top of the True boots slightly, and this seemed to help even more. Noticed virtually no heel issues during the first skate with them.
I actually think the conforming wrap wasn't allowing me to flex forward enough and almost acting like a hinge point. Instead of flexing forward and my heel driving back, I was essentially levering on the front of the boot and bringing my heel up.
Dont' know if this makes any sense, or if I just got lucky....but these two tricks seemed to have helped significantly and thought I would pass it along.
