With only those pics to go on it's hard to really tell how much the toes are bevelled, length of heels, etc. It does appear, from the hooves on the ground pics that they have been bevelled/rolled to relieve some ground pressure, at least on concrete(which unless the horse lives/works on that, doesn't necessarily count for too much), but I too don't think it is not far enough, especially at the toe, to relieve forces that will exacerbate separation & flaring. There is no need for getting rid of the flares entirely from above, but they do need to be addressed with regard to ground surface. If you look at the solar view, there is a fair proportion of foot out in front of the frog apex, indicating a bit of 'stretching'.
Other points I got from the pics are; the front feet look a bit imbalanced, being longer medially. Of course without further info not sure whether this should be just immediately 'corrected' with trimming, whether it's the camera angle, etc... And of the solar shots again, it does appear that little wall thickness has been rolled(I'd probably take it right back to the white line around the toe region) and it looks like the quarters & heels could possibly be lowered a tad more. Also in the lateral pics, it seems that she still has a bit underslung heels, but IME that will likely resolve itself when the toes are backed/bevellled effectively.
I would also trim/treat that crack on the right front toe which looks like it may also be infected.
Have read through all this and cannot find where hoof testers have been used to determine specific area of pain in the foot.
Until you find out exactly what's going on, it will be dificult to treat.....
Rings/ridges in the feet could be from heel pain or sub-clinical/mild laminitis. The fact that they get wider at the heel sugests pain/soreness rather than nutrition.
BNT, I appreciate that hoof testers can come in handy, but if you're implying that they are at all necessary
to know what's going on etc, I disagree. I just don't think they're anywhere near accurate enough to say anything exacting.
Regarding ridges/rings, I agree with most of your above comment, except the bit about wider at the heel suggesting just heel pain rather than lami. Interested to learn why you think this, when it is generally held that heels of laminitics(particularly those with 'rotation') appear to often grow quicker at the heel & have more buckling/tighter rings at the toe. I do agree though, that it's not just
laminitics, as horses with heel sensitivity tend to land on their toes, stressing them more & heels less.
