How to tie world's fastest shoelace knot

Premature optimization is the root of all evil. -Donald Knuth

So the love of money placed before the love of God is premature optimization?

18y agoHN ↗

I've been tying my shoelaces like this for the last six years. It is definitely worth the investment, if only because you spend less boring time tying your shoelaces.

18y agoHN ↗

this should free up at least 30 minutes of my day

18y agoHN ↗

Surprisingly interesting. You look at it and think, oh, of course it was a square knot, how come I didn't think of that? These things are so common and motorized that nobody cares to think of another way to do it.

18y agoHN ↗

There's something abnormal about having a site dedicated to shoelaces.

Anyway, this knot will shave about 5.5 seconds off my daily commute. Thanks!

18y agoHN ↗

This is the kind of hack you can really appreciate.

I've been using Ian's Secure Knot from the same site for a few years now, after my slippery-shoelace problem reached such crisis proportions that I preferred to spend an hour Googling for, and learning, a better knot, than having to keep retying my shoelaces.

The new knot has never once accidentally come undone, and is about as quick to tie and untie as the Standard Knot -- maybe even a little faster.
