Barefoot is a wonderful idea, but not practical for a wide variety of horses or conditions. The massive industry of hoof boots that has emerged over the past decade is proof positive of that. It's all nice tulips and buttercups to go "natural" and thing you're doing a great thing for your horse, but that warm fuzzy feeling is often replaced by frustration when your horse gets sore every time it rains, the soles shed, there are rocks in the path, the hoof boots don't stay on, and the diet has to be just right. For a pasture puff that no longer gets ridden, sure barefoot is fantastic. But for the vast majority of horses, shoes are needed both for comfort and for the horse to be able to do the job at hand. If, after a year of being barefoot, your horse is still ouchy on some surfaces, you don't need to adjust anything, you just need to put shoes back on.
