It depends. There are men who are generally taller and bigger than others, and everything really is bigger. They then also have bigger shoes. But I doubt that you could say it in general for all people.
I heard from a few women that instead of the shoes or nose, the size of hands and thumbs gives a good indication.
Nevertheless the size has to do much which genetic. People in Asia have smaller penises than in the western world, but probably similar shoe size. And people in Africa than have longer penises than people in the western world.
Therefore genetic plays a more important role than shoe size.
Then also do not oversee that some men use surgery and other methods to have an enlargement. You would not recognize it just with view to the shoes size.
Well and of course there are two kinds, blood and flesh penises. A flesh penis normally seems to be very huge, while a blood penis seems to be small. But in action a flesh penis does not grow much while a blood penis can grow to multiple size.
Further it said that up to 30% of the penis stays inside and only in action move forward. This makes it pretty difficult to measure size a all.
