Can anyone explain how people are able to walk over 600 degree Celcius coals bare foot and not have their feet burnt?

Coal and flesh probably aren't good conductors of heat. Pretty sure the sole of a foot has a lot of extra thick dead skin, too.

Also, your body is like, one giant heat exchanger, so extra heat will be transported quickly away from the feet, which helps keep them cool.

Also the feet aren't in constant contact with the coal. It's brief contact, then in the air, being cooled down, brief contact again, etc. People also only walk over them for a short amount of time, maybe 10-30 seconds.

And all that aside, I'm positive if you actually checked around, you'd find plenty of people with burns and blisters on their feet from trying to walk on hot coals and failing.

Disgusting layers of calloused dead skin.
