Don't feel bad about putting on shoes. I am a farrier. Some of my customers go the barefoot route, but some live in more rugged terrain, where it is not fair to their horses to let them go without shoes. Ferrel horses would be a completely different story because they have had time to adapt to their environment. But domesticated horses have been bred for many purposed in the show pen, and sadly, not every horse gets perfect feet. Out in the wild, only the strong survive, leaving easier keepers, but remember most people deal with domesticated horses. Find what is right for you in the way of what type of shoes, but I would highly suggest some sort of protection, before your horse's hooves become worn down into the sensitive lamina.
