What Causes Bunions?


Bunion causes have been a matter for debate. Some believe they are caused by tight shoes that pinch the toes together and force the bones out of alignment. Others believe that—since everyone who wears tight shoes doesn’t get bunions—hereditary foot structures were a more likely cause. In any case, tight shoes can speed up the process by keeping your toes from lying flat and straight.

Biomechanical issues from overpronation (flat feet that roll too far to the inside) can over time move the bones out of position. The big toe tip leans toward the second toe, and the joint where it joins the first metatarsal gets bent into a shallow V, which produces that bump that sticks out at the base of your toe. This protrusion makes it difficult to wear shoes, because it rubs against the side and becomes irritated, inflamed, and painful. The toe can also become stiff, with a limited range of motion. Arthritis, injuries, or leg length discrepancy could also be factors in their development.
