In reply to kean:
I think it depends on the damage to your feet, you shouldn't be out of pocket eg medical fees, helicopter ride, off work etc. It's not as though you are an ambulance chaser, so I think, yes, he (or his insurers should compensate you).
It's not really a matter of "blaming" him, he cocked up big style. No-one can avoid the fact that in such crowded circumstances he should have been more careful and you suffered as a result. You are not trying to punish him, or capitiise on his negligence, just want to be put back as close to the same as you were before it happened.
Probably best to claim on your own insurance. They will pursue him if they think it's worth it, but that needn't concern you once they've paid you.
