Rather than speaking about the sole being flat which could be misleading, I'm referring to the uniform thickness of the sole, front to back and side to side on a healthy foot.
The thing that bothers be about the term "flat sole" is that is exactly what happened when Hondo was foundered.
And agreed, all that actually address the physiology of the foot say it is arched if left to it's own devices as I have also witnessed on horses I've worked on.
So again, I'm not speaking about anything being flat on a hoof. Uniform thickness of the sole is what I'm talking about.
But as I type, it's dawning that if there is uniform thickness as claimed by those who claim to know, and since we both agree there is an arch, then the coffin would have to be tilted at least a little when the foot was unloaded. Then possible flat when loaded as claimed by some.
Perhaps this is the reason for the different opinions in the posted articles. I have not read any opinions where the degree of angulation is suggested while referring to the loaded and unloaded foot.
Ramey's discussion on his very successful protocol for reversing distal decent and P3 rotation very clearly in words and pictures says trimming the heel to gradually bring the coffin bone to ground parallel is paramount to his protocol, particularly for rebuilding sole thickness and concavity at the toe. But again, he does not specify a loaded or unloaded foot.
As I recall, Gene O. says 3 to 5 degrees but 0 is ok, but not negative. But again, I do not recall any comments about whether the foot is loaded or unloaded
Gene O. does of course talk about the arch as doe Ramey, but not when talking about the degree of angulation of P3, although they do talk about the arch coming from the angulation of P3.
For now, I'm going to conclude that when they are speaking about ground parallel, they are speaking about a loaded foot, and when they are speaking about the arch and angulation, they are speaking about the physiology of the unloaded foot. (until I learn otherwise)
I would agree that most domesticated horses do have some angulation even when loaded but lean toward the notion that this is not natural and is a result of shoeing, bad trimming, or both.
Sorry about the meandering long post..........thinking out load at 5 am on my second cup of java........
