I kinda gathered that they were part of a footwear because they're part of the boots upgrade, but yeah, I had to look up the term afterwards
I'm too old to know what Phineas and Ferb is, but when I was young I used to love knowing obscure words like:
The indent between your upper lip and your nose is called the philtrum (more commonly known now because of piercings
The recess on the bottom of a wine bottle is called a punt.
The infinity symbol (like a sideways 8) is a lemniscate
The cap on the pointy end of an umbrella, or any other tubular thing (including a pencil) is called a ferrule
The space between your eyebrows is your glabella
Etc. Anyway, aglet was one of those. I was always so happy when I had an opportunity to use one ("Oh, man, my aglet broke!").
And the infinity symbol is likely related to the analemma, the shape the sun traces out over the course of a year.
But are you old enough to remember Tom Cruise discussing them in the film Cocktail? (in the cinema on the original release‽ )
Easy. The 80s and older crowd will know this from some inherent eldritch knowledge or have no idea. But everyone else will know this from Jimmy Neutron.

I'm only in my mid twenties. Y'all need to stop making me feel old.
I watched Jimmy Neutron, but I guess I never saw (or maybe just never processed) that episode.
