Yes. bunions are definitely hereditary according to the podriatist I saw recently. I can't really remember all his explanation but basically ,you inherit bones which are a bit more bendable than most, so they get pushed out of position and bunions develop. I have large ones, plus plantar fascitis and very wide feet, and am rarely without pain. Oh and I have attacks of gout as well.
I used to look forward to Spring / summer when I could get into Dr Scholls or Birkenstocks or similar, but even they are no longer comfortable. I have one pair of shoes now that are as comfortable as they can be, from FitFlop, which are clog style and called Shuv. Even though they look rather wintry I wore them the whole of last year, even in the house when baking or doing anything which entailed standing for a lenteh of time. . Very recently Fitflop have come up with another Shuv clog but with open toes, so I was delighted and bought a pair - at great expense. Sadly they were not wide enough and I've just sent them back. Am wondering whether to try a half size larger.
Meanwhile I shall investigate Calla and Van Dal!
