You haven't heard about trimming to precise measurements & angles - even if feet are so far out of that 'mold' that they bleed when you do? Haven't heard about carving 'concavity' into a sole that doesn't have it, even if that means you leave it this enough to yield to pinky pressure??
**I do only have her original textbook to go on, and secondhand experiences - never met the woman herself, only seen & heard trimmers that did her workshops & seen horses lamed (sometimes for many months!) from that sort of approach. I agree with Desert that she did indeed have some good ideas, especially regarding management, but as with everything, anyone's ideas should be taken with a grain of salt & not accepted as gospel. As she is a vet, so *claimed* scientific 'proof', as she was one of the earliest and outspoken practitioners/teachers when there was still so little actual research or even anecdotal stuff, it did get taken up rather fanatically by many & I think this is a big part of people's bias against 'the fanatical barefoot movement'.
