The Physics of Shoelaces Becoming Undone

Here is a physics-based explanation of why shoelaces become untied so often: A "mix of inertia and pavement pounding loosens knots, sends ends flying".

I gave up on shoelaces very early in life (important life hack!). Of course, I never could tie the damn things in the first place, and I still can't.

The authors of this research may well have Ig Nobel prizes in their future (perhaps awarded jointly in physics and in fashion).
