The second and the third drawing show a shod hoof; the former when shoe has just nailed on, the latter some weeks after. Note that when the walls grow up, there is no more contact between le sole and the shoe; the gravity stress from the bone column is only sustained by walls laminar connections, without any solar/frog support. In the opinion of Pete Ramey [1], a resulting, slow downward movement of bony column into the hoof capsule results, as showed by "long walls" and apparent "upward coronet displacing" (sometimes, with conflict between the walls and the P2-P3 joint) in middle-aged or older shod horses.
