Most fakes are made by people using wooden plates carved to the size and shape of a Sasquatch footprint...On the other hand, we have evidence like this cast from the Freeman case showing the toes sliding back in the mud.
A more sophisticated method of faking Bigfoot tracks emerged in the later 1980s. A number of tracks and footprints began to be found... They had been made by a soft foot-like object, but while they showed dynamic interaction between the foot and ground they did not show the foot or the toes moving or flexing in any way...
Interesting, as the Patterson Gimlin Bigfoot film and other tracks found previously at the time in the area were in soft soil. I'll hazard a guess this has been the case in many other track finds.
In the following videos Dr. Jeff Meldrum, a Full Professor of Anatomy and Anthropology, as well as fingerprint technician Jimmy Chilcutt, who is trained in identifying even primate dermal ridges, debunk the argument that Bigfoot tracks are all fakes. Those who make this charge have often never even studied the intricacies of the footprint evidence, a very pseudo-skeptical approach.
