I have a funny story about shoe soles melting.

Several years ago me and a couple of mates went to Bathurst for the big race, the event lasts 4 days.
We had our camp setup on top of the mountain there with our tents arranged in a semicircle around a huge bonfire.
The bonfire was kept burning 24 hours a day, cause it gets cold up there.
One night, after consuming vast quantities of alchohol and other substances, everyone was sitting around the fire. We had scabbed up several sofas for our comfort.

Well one guy was sitting on his sofa with his feet pointing towards, sorry twoards, the fire. He was wearing steel capped work boots. Looking at his feet it was obvious the soles were melting.
Someone threw a full can of beer at him to wake him up, it worked extremely well. Anyway, as soon as he awoke he started dancing around like someone had set his feet on fire. He ripped off his shoes and went for a walk on the cold grass of the cap site while we all doubled after laughing.

The next morning when we awoke, he was looking for his shoes, they could not be found. Just then someone noticed a small D shapped piece of metal, then a second one. His shoes had completely melted, only the steel toe caps remained.

He was forced to wear flip-flops the rest of the camp and earned the nickname HotFoot.
