I'm definitely no professional or vet, and I've only taken a class on equine hoof radiograph reading during my biology degree.
I looked at the photos before I read the blurb above them. The only thing I personally see is the upright pasterns. Was going to point that out but then noticed you already mentioned it.
Other than that, I don't see anything concerning... I see no cracks, chips, pinches, arthritis, etc.
Again, not a professional, but his feet looks good and he looks great! Did the vet have anything to say about the radiographs?
