Testing one shoe with my standard double knot and this secure knot. I'll update with the victor.

I think your sample size of one is not going to be statistically significant. However I do think that in this case, the plural of anecdotes might actually equal data.

True. It's going to be ongoing, but it's already holding better than my standard double knot. Switched the other shoe to it too.

Also, keep in mine that I like to tie my shoes once every week or so and slip them on/off as I use them.
