All good points but, you wouldn't have to be clever at all, nor go to the trouble of emulating a mid-tarsal break, lets just say the bar is pretty low for what's accepted as a "genuine" bigfoot track.....laughable so. Maybe go back and review the Elbe trackway thread, that was some hilarious stuff.
You might be jumping the shark with how much trouble it would be to hoax a print, my assumption is most print's are presented by the people that made them, any others are just confirmation bias run amuck.
As I've suggested and it's what I do, take any claim and do a little research outside the world of footery, not trying to send you on a snipe hunt, just trying to encourage a little independent thinking beyond the echo chamber one can get caught up in at times.
