Professor Shoelace Gives a Lesson in Tying the Ian Knot, The World’s Fastest Shoelace Knot

Ian "Professor Shoelace" Fieggen gives a lesson in tying the Ian Knot, the world's fastest shoelace knot. The simple knot ends with the same result as the traditional shoe-tying method many people learn as children, but is achieved in a much faster way with fewer steps.

The knot only takes a few tries to get the hang of, and once it's mastered it can be tied almost instantly.
