Bunions are an arthritic enlargement of the big toe. They can be caused by footwear, injury, genetics or most commonly by overpronation or flat
feet. Bunions develop slowly over time. However, the speed at which they develop can be slowed by dealing with the factors that are causing them. Proper fitting shoes, bunion shields and custom orthotics to control abnormal mechanics are all treatment which can help. Severe and painful bunions may require surgical correction.
