Why Support the Three Arches of the Foot?

By Mark Charrette, DC

The feet are the foundation of support for the pelvis and spine. They provide the necessary stability to perform daily activities. Central to the success of the pedal foundation is its arched structure, which is actually a complex of three bony arches: the medial longitudinal arch, the lateral longitudinal arch and the anterior transverse (metatarsal) arch.

An evaluation of the anatomy and structure of the foot reveals that these three arches form a plantar "vault."¹ This architectural design optimizes strength, permits sufficient flexibility to accommodate changes in terrain, and provides propulsion for locomotion. The foot's arched structure is not present at birth, but develops during childhood, by age 6 or 7 in most people.² 

 Because the feet are under continuous gravitational pressure when bearing the body's weight, breakdown in any of these three arches can result in abnormal gait and transmission of asymmetrical forces into the pelvis and spine. Let's briefly examine the functional capabilities of the three arches individually, and then address the effects of arch dysfunction and what can be done to support a collapsed arch.
