Or grab a fake foot with your hands, press it deeply in to soft soil/sediment, heel first, then the fake foot's front, simulating the movement of a real foot.
Explain any marks you left with your own feet or knees while faking the track as produced later, while you were investigating and casting the tracks.
You can also hide marks made during the hoaxing process above described either by standing over a broad plank or thick cardboard (thus reducing the pressure over the ground) and/or standing over hard soil patches.
Jus noticed that since there was a nearby creek, another interesting approach would be to dampen a patch of dry soil untill it gets soft and then fake the track.
Footers must realize there are many ways to hoax things. Much more than they can usually think of.
The track below, btw, was made by me, shares similarities with those made by Tube and shows some aspects similar to the famous tracks with the silly mid tarsal break prints. I made them while using some heavy boots and stepping on gravel. This sort of material usually is not good to produce tracks; one could say only something heavy would be able to do so. My weight back then was a something between 83Kg and 85Kg. How I made it? Simple. Walked just over the parts with loose gravel.
