So this farrier only started in feb? This is only after his first session with this horse? So as this horse has substantial probs that won't be fixed in 1-few trims, we need to keep that in mind
So IMO... You can't fix a problem using the same logic that created it & I think in this case, the shoes are definitely compounding the problem. She needs her walls UNloaded and the soles & frogs supported/loaded, for the walls to be able to relax down at the back. She needs her heels pulled back, as in 'bevelled' in relation to the current 'ground surface'(assuming there is one).
Her hind feet are imbalanced - it appears he's pulled back the outside heel of the left hind but the rest are still crushed forward. It's unclear how much the toes have been 'dubbed' - that is, backed up on the surface & rasped high up the wall(not a good practice IMO) - but the 'bullnose' appearance of all feet, particularly the left fore & right hind really concern me. Can't tell much of soles from these angles & with the front soles half covered, but looking at the shape of the dorsal wall, the degree they're crushed, the hoof pastern angle, etc, I would be concerned that P3 on the worst 2 at least may have a negative ground plane angle. While IMO it's imperative the heels are raised to correct this situation, this needs to be done with support *under* the foot, not under the walls, which especially when already crushed, can just allow the rest of the foot to 'sink' further.
The massive flaring & imbalance on the front feet will also be exacerbated by being shod. Again, the walls need to be UNloaded to correct this, rather than forced to bear the whole load. The walls are already very compromised, so keeping them fully loaded has caused them to start to collapse & 'splat', as you can see most clearly on the medial sides.
