My farrier did explain to me why it is that the heel grows faster. From what I understood (and please correct me if I am wrong) the heel grows faster for a couple of reasons... One being that most of the pressure is at the toe which pushes the blood to the back of the foot making the heel grow faster, the pressure also causes more wear on the toe preventing it from growing. Also, because more weight is being put on the "good" foot, it has the same effect.
It's called a physiologic response and is the animals means of compensating for the relentless pull of the DDFT on the distal phalanx. The more you lower those heels, the greater the DDFT pull.
She also told me that lowering the heel will put more pressure/pull on the DDFT. She said that over time, the tendon will stretch and adjust.

She's half right. Yes, lowering the heels will increase DDFT pull on the distal phalanx. No, tendons do not stretch/adjust. If the DDFT were not so strong, it would simply tear. Not to fear though... the interdigital laminae almost always fails before the DDFT tears. That's why the coffin bone rotates, compressing the vascular bed, resulting in the compromised sole tissue at the toe and the remodeling of the solar margin of the coffin bone.
Eventually, the anterior of the hoof wall simply detaches from the coffin bone and can literally be torn away. You provided excellent evidence of that in an earlier photo.
If one chooses to remove horn at the heels, it becomes necessary to restore that caudal elevation through orthotics.
Managing a club is always best accomplished by using a lateral radiograph to determine optimal phalanx alignment.
Too much heel???
Actually.. not enough.
Forward running distortion of the capsule...
Remember... the clubbed limb will be functionally shorter than the contralateral limb!
I put a #3 bar wedge on the club foot and a #2 bar wedge on the opposite foot. The horse then presented level through the shoulders as viewed from behind.
