While I have tailors bunions and the start of regular bunions on both feet, I have not had surgery and don't intend to. It's my understanding that the bunions can come back after surgery if one doesn't determine the underlying cause of them in the first place. I personally blame shoes for my bunions as I have very wide feet and it wasn't until the last few years when minimalist / barefoot shoes became a thing that I could finally buy shoes that didn't crush my toes together. Cycling shoes are almost all designed with toe-crushing toe boxes and my toes hate them.
