I know pulling shoes and keeping your horse barefoot is the best thing for your horse, but you need to come to that conclusion on your own. I cannot convince you of that, but if you educate yourself and look at all the successful booted and barefooted horses on the trail, the results and performance speak for itself.
I encourage potential barefooters to do more research about natural hoof care, in particular, Pete Ramey and Jaime Jackson's studies. The both have books available, Pete Ramey's "Making Natural Hoof Care Work for You" is an excellent introduction to this way of keeping your horse. Available from Amazon.

These information sources will answer most of your questions and give you a greater understanding of what natural hoof care is about.
If you have specific questions, please call or email me. I really like to see my clients get educated in natural hoof care first, before we pull shoes, so that the horse can benefit, there is much more too it than just pulling the shoes and trimming.
