[Marvel] How does Spiderman stick to walls through shoes?

From what I understand Spidey has tiny hooked hair that allow him to climb flat surfaces and I can suspend my disbelief to the point that his gloves are fine enough for the ones on his fingers to still work but I cannot think how they would work through the soles of his shoes.

The hairs thing is actually in the minority of how their powers work. Spider-Man's ability to cling to surfaces is closer to his Spider-Sense where it a massive exaggeration of what spiders can do.

Wall crawling is more about creating attractive forces between Peter and whatever he is clinging to. He's essentially creating molecular bonds between himself and that surface in order to stick to things. Which is why he can often be shown wearing relatively thick shoes. The power comes from his skin but isn't limited to it.

This also why it can have the most absurd adaptations like Kaine's burning mark or Mayday Parker who can stick other people to surfaces sort of like magnetism (another force wall crawling has been compared to), something she claims the rest could probably do to if they tried.
