Also need to consider the square inch of press... 2 tons over 1 Square inch isn't hard, considering a high heal shoe spike can apply ~1 ton pressure over 1/4" sq.....
In this case it is quite a lot.
I don't understand the high heel analogy, could you help me? Is the wearer very large, or are you referring to stomping or something like that?
Well, that's a bit of an exaggeration, but right in principle...
If a person weighs 200 lbs is standing on 1/4" spike, that's 800 psi. Doesn't quite work out that way, because SOME weight is on the front of the shoe, and there are two heels. If you narrowed the heel down to a real spike, pointy and all, could clear 2k psi easily, I suspect.
