If you can find a farrier in your area that uses their methodology, you have found GOLD. I'm not kidding. Before them, I never knew the true importance of proper trimming/shoeing.
Healthy Stride is a system that focuses on balancing the entire horse, and fixing the alignment of their skeleton. I'm amazed at how much you can adjust a horse's entire posture just by changing his feet. If you give this vital aspect of your horse's care the attention it deserves, you'll be amazed by the results - his performance, and even his every day comfort will be drastically improved.
Please, do your horse a favor and check them out! :)
