I was once told that my wide feet were because of my Finnish heritage. I said "How so?" This is the theory.
My ancestors are from Finland. The Finnish are known for fishing. Wide feet help you keep your balance. Especially on a boat. Thin footed fellows washed overboard. Since they washed overboard they never had kids. Only the wide footed survivors were left to breed wide footed kids.
Convoluted and odd with a hint of truth. It made me like my feet again. For about an hour.
