The cause of bunions is inflammation of the tissue or bone at the joint of your big toe. A bunion causes a bulge at the base of your big toe. This bulge protrudes outward, and the deformity can cause your big toe to turn inward. It’s a hereditary condition, but poorly fitting shoes can be a factor.
The bump of a bunion is partly due to the swollen bursal sac and a bony protrusion where the first metatarsal bone and big toe meet. Bunions can occur for a number of reasons, but genetics is an important underlying factor, particularly when it comes to the angle of the first metatarsal. Wearing shoes that fit too tightly can also contribute to the development of bunions.
Bunions appear to be a bump or enlargement at the big toe joint. While this is true to some extent, in most instances there is a dislocation at that joint. They are often thought to be inherited but what is really inherited is the abnormal foot structure that causes them; i.e., most often excessive pronation or a rolling in (flattening) of the foot. In most instances correcting excessive pronation will prevent bunions. Another misconception is that women get them from wearing pointed shoes. While this can contribute to bunions it is not the cause. That is why some who wear such shoes don¹t have bunions while others may only have them on one foot.
While bunions can sometimes be genetic, wearing high-heeled shoes is often the culprit. What classically happens is you step in these high-heeled shoes and you squish your toes into the bottom of the shoe, and the toes kink a little bit, which makes the bone stick out.
There's no need to worry about bunions if they aren't hurting. It's not a big deal unless they bother you.
The best way to avoid bunions is to avoid shoes that are likely to contribute to their development. Once the angle starts to go off the wrong way, your foot becomes inefficient as you walk. That's why younger women in particular ought to pay attention to this issue.
