I adore this picture. In addition to being just plain beautiful, it is also a gorgeous example of "point of balance," or, global symmetry. A concept that transcends our common-place notions of [forced or specific, line, angle, curve, or ridiculous square=symmetry] biomechanics.
Physical biological systems can be more or less "square" as we observe them. They can be more or less aligned in lines and arcs. But they all have the capacity for brilliant biological and physical balance. They can all be "true," which means that they are at the best, most intelligent, graceful and organized a structure, orchestrated around a global point of balance, as is possible for the moment. They have a living, dynamic, breathing, and healthy balance point, and healthy biomechanics, as a result.
Tinkering with the length of this woman's feet, the height of her heel, the length or height of her toes, or applying a metal rim to the bottom of her feet would not enable her, whether she were born with or without obvious bone deviations from the average human dimensions, to have better physical orchestration. In fact, it would only add to her physical issues and reduce her chances for physical success. We know enough to understand for this woman, and for us all, to improve our biomechanics, we are talking about 4 dimensional physical development. Yoga, stretching, breathing, sport, machine-based exercise, stairs, socializing, loving, body awareness, eating healthy, species-appropriate behaviors and motion, laughter. These are the 4 dimensional, complex, things that will improve her biomechanics. If we can add to that physical therapy, an expert's eye and understanding of soft tissue development, compensatory movement (its usefulness, its limitations and its correction), symmetry building exercise and neuromuscular unilateral and bilateral (and really 4 dimensional) knowledge and expression, this woman will feel and perform her best. Never, ever, will we be so off track with her as to pervert her natural foot structure into something forced or unnatural. Yet, that is precisely what constitutes common care practice for the equine hoof.
We can do better, at least as well as we do for humans, in supporting healthy equine biomechanics. It simply starts with the overriding goal in horse ownership and health care of supporting the best physical development and use of the horse independent of our historical notions of what constitutes "the domestic horse and our experience with him." In other words, it is simply the living expression of a simple idea.
We can communicate and enjoy our lives together, man and horse, with no absence of performance, safety or creativity under the first, orchestrational, goal of healthy biomechanics.
