Althoug you did mention a air blatter tougne I believe ( I have no problem with that) Man those old conformable moldable tounges! remember those? we had to master perfection below to even attempt shootiong those old tounges in the day!
Again my point of view only! I love your research and analogies!
My guess is this is unlike anything you have ever tried or been exsposed to Ruidi. On the other hand I have no desire to try to convince you, other than to say that there is nothing crushing about it. What it does do is allow the foot to work in the normal needed fashion, yet it maintains optimum foot placement in the boot and contact with the bootboard. Maintaining foot placement by pressuring the sides and lower top of the foot (traditional means) is counterproductive to natural foot movement and it still doesn't maintain contact of the foot with the bootboard. The other plusses are increased circulation and sesitivity, both of which contribute to greater balance control. As Tristan Roberts said in his book "balance and Human locomotion", balance is about recognition. The modern sk booti does everything it can to take this recognition away from us. The instep pad along with effective ramp angle and forefoot room gave me my recognition back to a large degree.
All those issues of leaverage, in my humble opinion, are handled very effectively by the boot cuff and lower leg. Are the pressures under the foot really any greater than everyday semi-strenuos activeties create? It sure felt like it to me when my foot was pressure from the sides and lifting on and off my footbed. But not now. Why does it make sense to put so much effort into custom foot beds, then squeeze the foot from the sides, and then still leave room for it to lift away from the footbed?
I'll quote a line from an email I got yesterday, I hope he doesn't mind me quoting him, "I always noticed something when I took off MacPhail's boot and put my own back on. My own boots felt like cheap clothes - tight in the wrong places and loose in the wrong places." That is just how it feels to me. Once you have experienced this setup I think it would be very hard to go back. Things change slowly and I have no desire to force anything on anyone. But then if a person doesn't try something, how will they truly know if it works or not? Later, RicB.
P.S. How about the bottom of the foot and boot, and the cuff and lower leg for power transfer?
