I dont know my 11's (I strictly rock I-Vs in Js) so you could probably get past me with the space jams, but a bunch of my boys sell shoes for a living, and I'm pretty sure they'd be able to point out the differences. Which white/navy Is do you have, the hightops with the silver swoosh or the lowtops with the black swoosh? Both of those were the first non OG colorways and are really underrated in my opinion. Super buttery material. I have them both, although they've had a lot of wear at this point.
