So simple, yet so overlooked. I wish I had learned this before my feet had become weak, floppy paddles (read more about that here). Sure there’s tibialis posterior, anterior, etc., + the myriad of intertwined soft tissues comprising your body’s tensegrity that have a role in controlling the arch too. But the majority of work anchoring the supporting ends of the medial arch, the big toe and the heel bone, is performed by the Flexor Hallucis Longus and the Abductor Hallucis – these are literally the soft-tissue ground the two ends of the arch seek to stand on! It’s also easy to understand why this information is so overlooked too: most of the feet we see, including in most anatomy curriculums, are deformed from a life of adapting to footwear that restrict and alter the feet’s natural posture! It follows that current conventional medicine would be based around propping up a collapsed structure from beneath, rather than teaching a body’s owner operator to bring a tensegrity structure online. There were almost no shoes that allowed proper structure! This not-new awareness is newly taking hold through the rehabilitative healing work of pioneering medical professionals treating and curing many foot problems by restoring natural foot form and function.
