People often wonder if bunions are hereditary. The answer is yes, but only to some degree.
This is because what you inherit is not the bunion itself, but the foot type from a parent. For example, if your mother had very flat feet, then what you’ve inherited is that flat foot. Now she’s got bunions, then you are likely to get bunions. But there are other factors involved as well, such as ill-fitting footwear. So, it’s not just hereditary factors responsible, but it does play a big role.
