I rectified that immediately by completely removing the heel posts, thinning all the plastic under the heel to almost nothing, adding 3 layers of 1/8th inch neopreme padding (2 on top of the heel cup, and 1 below), and adding arch reinforcement. When I asked again the same question, the smile on his face was something to behold!! I will probably end up redoing the orthotic devices, but for today I was trying to see why his "good stabilizing" orthotic devices were not helping. No one looked at the force of his heel strike.
Here is the schema I was for watching foot motion. The green is considered normal. The "loud or hard heel strike" observation for Kirk was crucial today to finding the why of his 3 years of heel pain. Gait evaluation wins again (at least another small battle, one day at a time).
I think this emphasizes that with heel pain, just controlling pronation is not always right, just cushioning the heel is not always right, but a combination of the two is crucial.
