BF or crazy person Print & Trail?

[NCBFr]

We are in a draught and the lake's shoreline around me have receded significantly over the summer and fall.  I took the opportunity to walk my dog around one when I noticed a weird looking foot print.  This side of the lake is a fairly remote and hard to get to area and it was the only print I had seen.  Looking closely I noticed toes which I thought was really strange as the exposed shoreline is littered with sharp rocks, protruding limbs, and all sorts of garbage tossed out by fishermen.  Looking closer the front of the foot was much deeper than the heel and it had about a 6 foot stride.  I followed the trail off and on for maybe a half mile when I noticed the front and heel were now evenly depressed.  I concluded the person was first walking then proceeded to run for a short distance.  Running on this shore with bare foot is extremely insane because of all of the debris.  Then towards the end of the lake it randomly walks in to the muck for about 50 yards, circles back to relatively firm ground and proceeds in to the woods.  I could not imagine going out in to the muck with shoes let alone bare feet.  It rained pretty hard 4 days ago so the trail had to have been created prior to the rain.  I circled the lake's north side and saw a similar trail but much washed out which must have been created before the rain.  The pics are not great because of the lighting but it was pretty clear that they were not shoe prints and were made by something with a very flat foot and no visible midtarsal ridge.  The prints are not large, maybe size 10-11, but the depth was significantly deeper than I could make even jumping up and down.  Attached are some of the pics.  What do y'all think. 

 

Also, this location is about a mile from a spot where my next door neighbor's son swore he saw a 5-6 foot bigfoot at night watching him ride his bike in their backyard last June.  He only saw it for a moment when he flipped on the bikes light.  I studied the location the next day and saw a couple signs of things out of place but nothing definitive other than someone/something took a lot of effort to build a hunting blind/nest 100 yards from the location and right by the lake.
