Yep, you can see from the xrays they have little if any rotation, but the bones have 'sunk' extremely low in the capsule and the horse is therefore very thin soled. It also shows that laminae are quite thick - separated but likely filled with lamellar wedge - between bone & wall. The tip of the toe & breakover is therefore a fair bit forward of where it should be.
I've attached one of your xrays which I've marked to point it out to you & show where I'd be bevelling/rolling the toe back to. The yellow striped lines show the thicken lamellar material. The blue line shows approximately where I'd bevel the toe. The red lines, at the top of the straight section of P3 & at the coronet band, show how much the foot has 'sunk', as they should be roughly lined up.
the farrier was also able to take off a lot more toe with the shoes than he would have without.
Why is that, that he feels he couldn't remove enough toe when he was bare? Especially if the horse is now shod, if you haven't already, please consider filling the soles with 'Sole Guard' or some other form of padding, so the horse isn't hanging by disconnected walls and his soles & frogs get *comfortable* ground support, so that they may begin to grow thick & allow the coffin bone to begin to raise back up in the capsule.
I definitely thank the shoes for this. I know it's very controversial, but I'm trying to do what I feel is best for him, and what will get him (and keep him) out of pain asap.
Yep, I may not agree with the approach you've taken, but all you can do is educate yourself as best you're able & do the best with the knowledge you have at the time. Good for you. Just make sure you stay open minded & keep learning all you can.
as soon as those shoes were on him you could see the relief, and it's great to see that. he's very obviously much happier.
Yes, raising thin soles from ground pressure does tend to relieve their pain. But as it doesn't allow the hooves to function correctly or address the cause, it is generally a palliative and temporary effect.
Regarding his diet, it's likely the grain that is at least part cause of his 'sensitive' system and weight issues, as previously explained, so great that you're cutting back. The sooner you're able to remove it from the equation the sooner his system will be able to start getting healthy.
I wish you & your boy the best!
