Spider-Man Would Need Size-114 Shoes To Scale Walls In Real Life, Researchers Say

Researchers have found Spider-Man would need much larger hands and feet if he were to scale walls in real life. That's because the superhero – and any human for that matter – would need a much larger body surface area equipped with far more sticky footpads to support his weight. That's why geckos are the largest animals able to scale smooth vertical walls.
