Luaan posted a comment on a question, as follows (emphasis mine):
Take an old-school shoe with no rubber, and you'll see that it's extremely slippery on wet surfaces - medieval Europeans went barefoot most of the time, especially in winter.
Is this claim correct? Given that Europe's winters are often freezing, how would someone be capable of walking around barefooted without getting frostbite, let alone losing their toes in sub-zero temperatures? I'd expect some sort of animal skin wrapping at the very least.
