Why do Shoelaces Come Untied?
Why do Shoelaces Come Untied?
Spoiler: It’s not laziness—it’s science. In this episode, we unpack the UC Berkeley study on knot physics, expose the aglet’s dark side, and lead you to the knots that never fail.
UC Berkeley Shoelace Study
Study Title: The Roles of Impact and Inertia in the Failure of a Shoelace Knot
Authors: Christopher Daily-Diamond, Christine Gregg, Oliver M. O’Reilly
Published: April 12, 2017, in Proceedings of the Royal Society A
Key Quote: “The failure of a knot occurs in a matter of strides, driven by dynamic loading of the aglet.”
