Studying, the form and function of all the structures of the equine anatomy and how they relate to one another is crucial for understanding how to maintain a sound animal. Central in this understanding is the proper weight-bearing and alignment of the coffin bone (P3)

in the healthy hoof. Correct breakover is essential for the animal to achieve its optimal stride which in turn contributes to its overall health.
The sole and frog are major weight-bearing components requiring suitable support for healthy weight distribution and blood supply.
For these components to function properly, the heels must be at the correct height and in the correct location. It is especially noteworthy that the hoof wall is not designed to be the major weight-bearing structure of the foot. Maintaining its thickness is critical for the strength and protection of the hoof capsule.
World wide research including studies of the feral horse, provide a better understanding of how the hoof functions according to nature's own blueprint. We have learned from free-roaming horses that the front of the hoof wall (the toe) is naturally rolled, curving upward like a running shoe, and is not a primary weight- bearing component.

The sole is weight-bearing, helping to support and protect the coffin bone (P3). The shape and wear pattern of the self-maintained, unshod hoof in the wild has an appearance much different from that of the domestic, rim-shod horse.
