The Argument for Orthotics
The foot is a wonderful construct of nature - it is able to handle weight far in excess of its own weight while being highly flexible. The anatomy of the foot consists of a web of 27 bones that are composed of 3 arches, the most common of which the medial arch. There is also a parallel lateral arch that is much lower and a transverse arch that is at the base of the toes going across the foot. It is the relationship of the bones within the arches and their exposure to the inexorable force of gravity that plays a role in pain in the foot in the form of bunions or plantar fasciitis and ranging to pain in the hips and low back due to differing leg lengths when one foot has a dropped arch.
