[Spiderman] Spidey seems to be able to hang upside down from a ceiling from just his feet regardless of whether he’s wearing his costume or a pair of sneakers. How does that work? Does his body itself exhibit some kind of magnetism that doesn’t require skin contact (or thin fabric) to stick?

I am not sure if it is different now, but for much of the 616 continuity, the wall climbing did not work through sneakers. When Peter Parker first married MJ, he was running late to the wedding and used spider powers to get there. He had to take his shoes off to wall climb and ran up to the venue with his shoes in his hands.
