I remember in a discussion on UMAA where this came up, and using my weight
at the time [100Kg] and a pair of my boots to get a baseline, and using the
MG RX78-2 for the Gundam, I worked out that it has a ground pressure 3 times
what mine would have been.
Now, a Dom, OTOH has enormous feet, and if it's about the same weight as the
RX78-2 would have a ground pressure *less* than mine...
I'll try and dig out the figures at some point...

It also depends how fast their feet are moving when they hit the ground.
Ground pressure really only applies when it's standing still. What's the
walking speed of a Gundam?
