A thickening, bony bump, often with inflammation of tissues at the base of the big toe joint that can form as a result of genetics, faulty foot biomechanics and pronation. Also made worse by poorly fitting shoes, including too narrow, pointy, or high-heeled. Sometimes the big toe remains straight, with just a bump at its base. In others, the big toe will become crooked, pointing towards, rubbing, under or overlapping the 2nd toe.
