Bunions have nothing to do with how much walking is involved. The formation of bunions is mainly due to two factors: 1. congenital hereditary factors. Many bunion patients have a family history of similar conditions in their families; 2. In the course of the day, if you wear more squeezing shoes or do activities that squeeze the toes, it may lead to a bunion. More common is the practice of ballet, because it requires long periods of standing on tiptoe, this time may cause a very violent squeeze on the toes, thus causing the bunion to occur. Another condition is that in the old days, due to the existence of foot wrapping, bunions were more common among foot wrapped patients.
