I'm a 6'1" (185 cm) man with stupidly small size 3 US (EU 34) feet. I've never met another adult with smaller feet than me.

As a baby I was born with a pituitary issue which meant my hands and feet were abnormally small. They never grew that large at all. I can run and walk fine and they're not deformed or anything, just tiny. I might have some weird world record for smallest hands and feet on a fully grown adult!
And a lot of converse chuck taylor styles like the dinosaur ones, lol.
