Dunno, Y'all may be making this too hard.
I started racing motorcycles with AMA in the mid '70's, have been racing cars since '84. I've instructed for SCCA, SVTOA and Integra R club.
Braking is the important part. The ball of the foot works great for this. Not the instep, not the heel. You have the power of the upper leg and the control of the end of the foot. I only use the right most part of the brake pedal and then blip with the little toe part of my shoe or sometimes even the side. I have scuffs on the side and even the top of my right driving shoe. Simpsons to Magnum duty boots it's the same. True you can feel better with a race shoe, but not necessary.
"heel"-toe works from street to autocross to roadracing.
John Baucom of TransAM fame was my roadrace instructor years ago.

He brakes hard and just moves his knee to the right. It is enough to blip with literally the side of the foot.
