"We should recognize that, on weight bearing, steel shoes hold the sole of the hoof in a non-weight-bearing, vaulted position against the descending coffin bone. We misinterpret so-called "stone bruising" of the soles of shod horses as being caused by stones on the ground. This pattern of bruising originates from concussion followed by pressure necrosis of solar corium that cannot escape the blows of the coffin bone above and an unyielding sole beneath. Bruising of the moonsickle points to a pathology at the tip of the coffin bone and originates because of excessive heel height."
