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!
My feet can ache a bit after a long day or a run but I don’t think significantly worse than normal footed people. I do have orthotics that I use for extra support. I guess one advantage is that I really do not stub my toes ever…and shoes are much cheaper for me in kid’s sizes. And I can wear light up shoes. Plus I can run pretty fast - I guess my feet are much lighter than most.
