I can't tell too much from the photos; it would help if the photos of the stance were more 'close up', and the horse standing on cement or asphalt so that the ENTIRE hoof was clearly visible.
In the sole photo, I see that there is a flare on the outside of the left front hoof; also, it appears that the frog may have been 'pared' more than I like to see(I only 'clean up' the edges of the frog, basically, so that "gunk" is less apt to become trapped--and of course, remove clearly 'dead' tissue.) I like the fact that there is a nice big wide frog,what appears to be a good, slightly concave but strong, sole, and a basically round and good-sized hoof--all 'pluses', in my book! It appears to me that the horse may 'toe out', minimally-really, only from the pastern down; perhaps he has been trimmed high on the inside to try to 'straighten' this slight toeing out, leading to the steeper inside wall and outside flare...??As I said earlier, this kind of thing has no lasting effect when done to mature horses, and *might* actually have deleterious effects.
I can't tell from any of the photos if there is evidence of truly uneven wear, however? The horse's hooves do look to be pretty short; is that what you were referring to?
Sorry, I can't really be any more specific based on the available photos/information.
