Wearing high-heeled shoes is an important reason for the formation of bunions, for the following reasons: shoes with heels that are too high, too thin and too narrow make it difficult to fix the heel, and create friction and pressure on the toes. On the one hand, it restricts toe extension and movement, causing pain and discomfort. On the other hand, it destroys the function of the original 3 footholds (when a person stands and walks, the foot is supported by the heel node, the 1st metatarsal head and the 5th metatarsal head, which together support the weight of the body), so that the support point of the foot is changed, resulting in the weight of the whole body falling on the front of the foot when walking. Because of the weak connection between the 1st cuneiform and the 1st metatarsal, wearing high heels for a long time will make the 1st cuneiform and metatarsal bones bear more than 25% pressure, prompting the 1st metatarsal to shift inward, causing the longitudinal and transverse arches of the foot to collapse, and the bunion to move outward due to the pull of the bunion and bunion extensor muscles, resulting in an increase in the angle between the 1st and 2nd metatarsals, eventually leading to the formation of a bunion. In the long run, the ligamentous tissue of the medial side of the big toe will relax and the joint will be subluxated.
