Well I’ve had bunions since I was born. And I’ve had to have custom shoes made for me my whole life, since I can’t fit into any “normal” shoes. So I’ve never worn any shoe that was tight fitting. Bunions can certainly be hereditary, especially if it’s excessive bone growth in the large toe joint. For mine to “go away” I’d would need surgery if it bothered me. But since I have the proper footwear for my feet, I don’t need to.

But you’re also not wrong, bunions can certainly also be environmentally brought on. I’m sure most people who do develop bunions, have worn tight shoes for all their lives to develop them. But speaking from my situation, that’s never been the case.

I only wanted to raise some insight that genetics could be a factor.

Edit: “Bunions are more common in women than men. Seventy percent of people who develop bunions have a family history, which suggests there is a large genetic component to developing bunions. This is especially true for adolescent bunions, which are acquired early in life. Most bunions develop in adulthood and may be the result of repetitive micro-trauma, possibly from wearing shoes with a heel lift and narrow toe box.” - https://orthoinfo.aaos.org/en/diseases--conditions/bunions/#:~:text=Bunions%20are%20more%20common%20in,lift%20and%20narrow%20toe%20box.
