I specifically asked if he had any signs of WLD or anything the last time the farrier was out.....This just might get complicated if he does show "seedy toe" "WLD" or any of the other dozen names for the separation I thought we had under control and done with.
OK, perhaps it is under control, but IME this sort of separation goes hand in hand with seedy. I would certainly keep up preventative treatment until you can get good hoof form & attachment. Yes, BTW, did notice thrushy frogs. Was going to comment that while I think it's great the farrier obviously doesn't go in for routine/over trimming of frogs, IMO it's best if those flappy bits were trimmed off, considering thrush.
The right hind is the twisted leg. It shows clearly in the pictures. He has pelvic issues that caused the twisting.
Yes, I can see that it's not quite right, but from those pics, it seems that both hinds are cow hocked & turned out a bit far? And what of the right fore? Is that as turned out(entire leg or at least from knee?) as it appears? His fores both appear a bit valgus from the fetlocks too?
With the body imbalances, you're unlikely to get his feet looking nice & square, so I'd be focussing mainly on keeping them well balanced in relation to the sole plane & rolled to address those flares.
I'm thinking you can see how stretched the front feet are(backs maybe a little stretched at the toe too, but hard to tell without more info/being there), but have included a couple of marked pics. The sole shot shows where I estimate the sole goes to, with the green line showing approx where I'd start a strong bevel in order to relief force on the walls to allow good attachement to grow down. The side shot shows approx where I'd trim the toe to encourage this.
