(Hallux Valgus)

The joint at the base of the great toe is the most complex in the front of the foot. Here the bones, tendons and ligaments work together to transmit and distribute the body's weight, especially during movement. Should this joint become abnormally stressed over an extended period of time, a bunion deformity may result.

A bunion (from the Latin "bunion," meaning enlargement) is a protuberance of bone or tissue around the joint. The enlargement occurs either at the base of the great toe or on the outside of the foot, at the base of the little toe. This is called a "bunionette" or "tailor's bunion."

Bunions at the base of the great toe usually begin when the big toe starts moving toward the smaller toes (as when tight, pointed shoes are worn). This crowding puts pressure on the joint, pushing it outward. The movement of the joint in this outward direction starts the formation of a bunion.


Symptoms Custom orthotics will prevent excessive pronation and reestablish proper weight distribution and biomechanics.  Weight is effectively absorbed and evenly distributed.  This will alleviate the factors, that over years, cause bunions.
