I can understand the car part (pounds per square inch) but why would a person's feet have more than 35 psi? If I have something like 60 (30 per) square inches of feet, and I weigh 180lbs, would that be 3 psi for my feet? Even if only parts of my feet were striking the ground at a time, how would that be more than a car?

High heels. Also in this specific case we are talking about metal spiked ice shoes.

Thanks, that makes it very clear.

All your posts are helpful.

For example, I never before considered the implications of tire PSI.
