It depends on the terrain in your area of the country, and what you plan to do with the horse.
The vast majority of horses will never NEED shoes. But there are a select few who have lameness issues that need corrective shoeing. And there are some events where shoes can enhance performance (you aren't going to see a reining horse do a sliding stop barefoot ... they need slider plates).
Chances are, your horse will never need shoes. But that is not a guarantee, of course.
