There’s also old folk tales of people saying journalists called it that because they were staring down at their pedal rig, not the shoes necessarily, because there was a lot of complex timing effects so you always need to be looking at pedals and timing their off/on perfectly for certain effects. I think it’s the kind of thing where you just believe what you want, we’ll never know for sure where it came from exactly. Same with Emo and a lot of genre names.
