Also, considering both hand size and foot size are correlated with penis size, that theory might run into trouble if both hand and feet dont similarly stay in proportionate size.
According to everything I've ever read on the subject (and to a somewhat lesser extent, personal observation), they're not in fact correlated to any useful degree. (Nor for that matter is there any particularly significant correlation between "race" and penis size.) To the extent this sort of thing has been objectively studied (and as one might imagine, it's not exactly the sort of thing that gets a great deal of close scientific scrutiny), there seems to be a very slight correlation between
height and penis size, but basically only just enough to be statistically significant at all. Mother Nature apparently has quite the sense of humor when it comes to penises, so one never knows what one's going to find until the proverbial fat
lady gentleman
sings , er, drops trou... (spanning the whole range from 5'5"/110lb guys with "huge" ones to 6'3"/220lb guys with smaller-than-average ones...) And even then, there's that additional and separate "grower" vs "shower" issue, too, so even just "dropping trou" doesn't tell the whole story. Not to mention that for no reason I can think of, everyone who obsesses about this topics seems to focus on length, with little if any mention of the (arguably more relevant) question of girth...

But anyway, for whatever it's worth, I generally wear an 11D in dress shoes and an 11.5D in sneakers/boots, though it varies among brands and "models". I don't know the actual measurements of my hands or my "official" hand size (if there is such a thing), but I wear L/XL gloves. I'm 5'8"/155-ish. But I'm afraid you'll have to at least buy me a drink before we start discussing the size of any of my body parts that isn't normally apparent when I'm in street clothes.
