I work in the boot/shoe business. In my experience shoe size is sometimes a reasonable guide to the proportions of the cock, even though a few of you guys appear to disprove it! But it's not just in terms of say Size 8 against Size 16. It's also about the type of fittings. Over the years, I have met a few guys with VERY broad feet whose cocks I have seen and they have ALL had bigger than average cocks - one remarkably so. It's only half a dozen over 20 years but without fail they have had longer than average wide cocks. A guy I dated many years ago worked at Heaven in London. I met him when he came in for some biker boots that were very fashionable and he complained to me that although he could find his size easily not a huge size, something like a 10 or an 11), none would fit because of the width of his foot. His feet were very wide. I chanced my arm and told him that was almost always the sign of a very big fat cock. I shall never forget the sly grin on his face and the fact that it was the quickest conquest I had ever made at that point. And he was extremely thick. Not so long ago I had two guys in the shop, who wanted Converse All Stars in Size 17 and 18. They were a couple and I joked about the size and one said that the other one was so big he had difficulty taking it.
