Wow I didn't even think about analyzing the shoes! It makes so much sense! So you're saying that purple boots is Riley, animal shoes is Maya, and combat boots is Lucas? That's some really sneaky foreshadowing 🙄😏
Purple boots is definitely a Riley nod, leopard shoes is definitely a Maya nod, but the motorcycle boots/Lucas connection is a little more dubious.
If the rebel shadowing Lucas in GM Friendship was meant to show a part of himself he was/is repressing (and with the rebel being credited as Brandon aka a nod to Colonel Brandon from S&S perhaps), then it suggests to me that at SOME point we are gonna see Lucas truly stop repressing and fully integrate himself in terms of who he used to be vs who he is now, a la Topanga in GM Popular. But I think for that to happen he’s going to have to go through something that shakes the foundations of what/who he thinks he’s “supposed” to be (I’m sure you can guess what I think that’ll be)…and that’s where leopard shoes comes in, maybe. (There’s also the fascination with Harper/her bike in GM New Teacher, hat tip to @lucayafever23! And Maya wore motorcycle shirts in the Forgotten and Gravity, hat tip to anon for reminding me.)
Oh, and then there’s Leopard Shoes & Motorcycle Boots being dressed similar to Maya and Lucas’s costumes color palette-wise for most of the episode I think, but I need to double check.
Motorcycle boots could also potentially be a Josh nod if you REALLY wanna reach using IRL stuff about the actor, but that’s WAY more dubious than the Lucas/rebel connection in terms of actual canon to tie it back to.
BONUS: Purple combat boots are a LOT like motorcycle boots, albeit not exactly. They’re more alike than either pair of boots vs leopard shoes though…
