My horse had very flat soles after 2 mnths with laminitis, when the shoe removed she was very sore and the sole was flat. But after 2 mnths the sole went back to the normal concavity again.
I think she felt pain in this time of recovering.
Ehhhh - do you mean that it is possible to make the coffinbone to derotate?
Uuuh, sort of descussion. (baaad english, I know) ;)
