I guess you didn't read the part about hair analysis labs getting fooled by synthetic hair in the article I linked you to. I'm also guessing that you haven't tried any experiments with such hair (I recommend Dynel).
Actually,
they have.
One thing that helped me "off the fence" regarding whether or not Bigfoot existed was
this site, which hypothesized that overlaid animal tracks could be mistaken for the tracks of a bipedal, humanoid animal (aka Bigfoot). Although convincing by itself, I decided to look into whether or not this was actually possible.
These links show tracks that have been confirmed as being overlaid bear tracks. Now imagine what would happen if those bears moved over one of their feet just a bit more. Instant "Bigfoot" track.
I was also lucky enough to find
this trackway, which consists of bear prints overlaid enough to show how a quadrupedal animal’s tracks can seem like those of a bipedal animal, but not overlaid enough to give the impression of a Bigfoot trackway. This was enough to convince me that Dr. Bruce Marcot’s work was indeed correct. I then decided to do research more about bear feet and how they compared to alleged Bigfoot tracks. I found that in some case, even non-overlaid tracks greatly resemble Bigfoot tracks.
Here's a supposed Bigfoot cast from Dr. Meldrum's website. Now
here is a picture of a cast of a black bear's hind paw (

Here's another picture from Dr. Meldrum's website and
here's a picture of the feet of an unconscious bear. I'm not saying the above bear made that track, only that it seems likely that a bear made it.
I find the resemblence between this
“Bigfoot track” and this
Himalayan black bear track to be astounding.
I showed those pictures to other people to see what they thought. They saw the resemblance, although it was noted that the Himalayan bear track picture had some grass covering a toe and that it would’ve been much easier to see the resemblance if the bear picture was “flipped”. I did find some
other,
similar pictures while doing Google image searches for bear tracks and bear prints.
Those seem to prove my suspicion that American species of bears can leave tracks similar to the Himalayan one.
I think I see signs of a partial track overlay in
this picture, and
here we have a bear track that looks humanoid.
This could certainly be an explanation for Bigfoot tracks that were supposedly found in places so remote that the chances of finding them would be unlikely (although it's kinda odd to say that, seeing as how people actually find said tracks by going to those "remote" areas). Combined with hoaxes and people mistaking holes and such in the ground for "heel marks" or "partial footprints," I'd say that we have a nice little skeptical package that explains Bigfoot prints. To be valid as evidence, all Bigfoot tracks will need to demonstrate that they are not the result of the above options.
