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).
