I hear patients all the time blaming themselves for the formation of their bunion deformities. They feel they wore the wrong shoes over the years. Well, actually that's not true at all.
The great majority of bunions come from an improper foot structure that you were born with. So, I guess you could say you can blame Mom and Dad for this also. It has very little to do with the shoes. While shoes can make a bunion more symptomatic once it occurs, they are not what caused the bunion to form in the first place. So, you do want to wear proper shoes when you're forming bunions, but it's not really the shoes that cause bunions.
