GPT-4o mini · Answer

The two pieces of evidence that support the connection between g-forces putting pressure on the knots and the body and spine are:

“Your foot is experiencing these really high g-forces as you’re running all the time.”
“The videos showed as the shoelaces bounce up and down with each footfall, the main knot begins to deform.”

These statements directly relate to how g-forces impact both the knots in the shoelaces and the physical stresses experienced by the body while running.
