Bunions are caused by abnormal biomechanics of the foot. This leads to structural changes and adaptations of the boney framework in the foot which causes a deviation of the great toe onto the second toe with the formation of the bump at the joint of the great toe. Bunions are not an inherited condition from family members. It is rather the poor foot mechanics that is passed down. Bunions if left untreated can evolve to be a very painful condition especially when bearing weight. If the bunion progresses even finding shoe gear that fits without discomfort can be quite challenging.
