There is no "correct way" to wear them
this is a straight up fact. Unless your wearing them around your ankles.
When I wear my typical gettup, helmet, my pull over facemask, and a bandanna, which is 99% of the time, goggles are on the outside so i can lift them up when need be.
If i forget my facemask or bandana, I seem to end up putting my goggles under my helmet to tighten up the fit.
Also depending on what headphones I have on me, goggle straps can provide that extra suttin suttin to make em fit right.
No right way, just different ways.
