Thanks for all of the replies and interest –– no strong leads, but a lot of interesting info has come to light. While I was long aware of his footage in the DC Clockers from "Menikmati", I never saw that blurb from Big Brother about him buying DCs at retail –– no local shops carried BB, and Barnes and Noble didn't carry it until '97 or '98. So there's yet another mysterious footnote to Tom: did he literally buy a pair of DC Clockers once, for any number of reasons –– and what was that reason –– which went on to have an outsized impact? Was he regularly buying them?
If it wasn't for that info, I would've just assumed the DC guys were trying to poach him and were giving him shoes to try out. As much as I love mid-'90s Etnies and éS, they definitely dropped the ball by not releasing his requested boot-sneaker pro model in the late '90s, and a '97 - '98ish DC Penny probably would've been sick as fuck. Going back to the topic at hand, I firmly feel that THIS pair was definitely not any released DC; maybe it could've been some prototype or sample that never came out, but that doesn't seem to be the case anymore.
I've always thought that they were most likely something obscure and of that time, like some Karl Kanis, or some weird sneaker that an outdoor/hiking company made (ala the Timberland that were later fully ripped for the Vita Jason Dill). They still might just be a Nike, though that Fila guess seems better with the shape/silhouette (thanks for that guess..it lead to a rabbit hole with me seeing the Grant Hill 1's for the first time in decades.)
