Go barefoot for now, if down the road it appears he needs shoes by all means get some slapped on. I've found most horses with sound feet handle no shoes, even on rocky terrain, just fine. I have a feeling most performance horses can perform fine with no shoes too it's just not attempted. Did read a story about someone racing a TB with no shoes, been to long ago to remember the details but the horse did well.
If your horse has hoof problems (navicular, foundered, etc) then odds are a proper set of shoes for their condition will improve their lot in life.
