Yes, it only took me.... 40 years to discover!
What you do is....
Tie a regular bow thing then go for the the next half knot where you tie
the loops on themselves in an overhand but (and this is the secret)
take the same loop that you went round and through with and do a 2nd
"round and through" before gently taking up the slack of the knot.
In a similar way to how it's possible to tie a fishing hook to
mono-filament line. The more wraps the better the grip but for a
shoelace only one extra wrap is enough.
Not only does the additional wrap eliminate any knot slippage even on
round nylon laces of walking boots etc but it also makes the bow lie in
the correct orientation across the shoe.
You can untie it really easily because it doesn't need pulling tight to
lock it and with a gentle tweak of the body of the knot as you take up
the slack it forms a nice barrel shape.
Knot perfection that can be untied even when wet.
You're welcome.
