A bunion is a protrusion of bone, forming at the joint connecting your big toe and foot. The bump is primarily caused by the bone of the big toe deviating outwards. This outward extension contributes to a wider foot, making it extremely difficult to find a comfortable pair of shoes. Over time, with bunions, your toe may no longer function correctly, making walking, running, jumping and moving extremely painful as each step puts more pressure on the joint.
Some people are genetically predisposed towards a bunion, and may have flattened arches and/or hypermobile foot structure that can promote the development of bunions. Those that frequently wear narrow footwear may also develop bunions. Finally, if you have a history of joint trauma, this can also lead to bunions.
