Didn’t get to read most of the posts, so sorry if I happen to echo advice already given or miss something 🙂 Anyway, here is my 2 cents on shoeing..... it can be very benificial for horses that wear their hooves down quickly, but usually only if the trim is correct beforehand. If the trim in imbalanced, then worse issues can occur such as sidebone, ringbone etc.. I find many people claim shoes help because the horse simply doesn’t feel as much with a shoes vs barefoot.
I have cavello hoof boots for my horse. They are okay, but I find they are bulky and not great outside of regular conditions (outside of a dry ring). There are definitely better options out there. I’ve heard renegades are good for trail riding.
I’d also suggest looking into your horse’s diet if ypu already haven’t. Make sure it’s balanced and he has enough copper as well. Copper, zinc and Iron should be at a 1:4:4 ratio as they are able to block absorption of on another. Also, it is common for thrush to occur in a copper deficiency. Often, copper is overlooked in diets, but helps alot in strength and growth of hoof. A good diet and proper trim can do wonders for a horse.
