Running shoes for small wide feet

This is a very embarrassing question. If you were an average person, what size running shoes do you choose (running 5-10K)? I've been running for 25+ plus years and I've always chose US size 6 shoes (EU 36) because that's what I was told when I was younger to accommodate for the expansion of my feet when running and my wide feet. My measurements usually leads me to EU 34.5-35 wide in other shoes and sports equipment so it is a big discrepancy in sizes. I also noticed that I have the grossest feet due to calluses and hot spots and wonder if that's due to ill fitting shoes.

I just ​bought vivo barefoot running shoes EU 35 to see if there are any changes. Any other advice?
