This is a frame from the Patterson Bigfoot film. Notice as the animation runs that the big toe is held straight up. When she puts it on the ground the big toe will not make an impression. The foot bottom is also bent to the inverse. It is convex in its shape. When the foot is on the ground only the front part of the foot will touch. I believe that this is deliberate in order to mimic the print of a bear. Take a look at the photograph here. It was taken by a bear hunter at Bluff Creek California. This bear hunter had seen the Bigfoot and saw it make the print. As you can see, it is missing a big toe and is only the front part of the foot. Perhaps it’s the same one in the animation.
