Due to a pituitary issue when I was younger I have maybe a bizarre world record of the smallest feet and hands on a fully grown man. My feet and hands are normal looking but very small. They were tiny as a baby and just never grew that big. Thought you all would find it interesting - I know it makes for good chat at parties!
I was born clubfooted and mine are smaller than average (for 5’11").
Length-wise I’m probably technically around a 7, but I have a super high arch that prevents me from wearing shoes that size.
I end up wearing anywhere from 7.5-9 depending on the fit. The toes of my shoes almost always end up curling up over time due to the extra empty space.
