Bunions

Causes of Bunions

There are several causes of bunions:

Heredity: some inherited foot types—flat or overpronated —are more vulnerable to the formation of bunions.
High-heeled, pointy toe, poorly designed or ill-fitting shoes.
Foot injuries that affect the big toe and little toe joints.
Deformities present at birth (congenital issues).
Arthritis, including inflammatory or degenerative forms, that cause the protective cartilage that covers the big toe joint to deteriorate.
Occupations or leisure activities that put extra stress on the feet or that are associated with pointed shoes (for example, dancers and wearers of western boots).
