ELI5: Why do your socks not feel sweaty until you take your shoes off?
gpt
Because you can't actually feel wetness (skin don't have sensors for that). But how do you know then? Well, your skin is good at detecting heat loss, so if it feel heat loss that match water exposed to air, your brain understand your skin is wet. But when you're still in your shoes, the wet socks are kept warm, and you don't feel that heat loss. That is, until you remove them.

That's why if you have latex gloves on, you can feel fake "wetness" if you touch water, even though water never touch your skin. That's because the heat goes through the glove then through the water and out, which trick your brain in feeling water.
