As an OG-head, I can tell you we hated when the midsole yellowed. Being a dumb teenager, and not knowing anything about how sneakers were manufactured, I spent countless hours trying to "rub off" the yellow from my WC4 and Trainer TWs midsoles. Absolutely HATED the yellowing. Honestly didn't notice it on the netting of the 4s and 5s b/c it happened gradually, and we all wore our shoes back then, so no one had a DS pair; heck, that term didn't even exist.
So not sure what JB is trying to pay homage to with this pre-aged crap. Certainly not honoring the feeling us OGs had with these sneakers.
I've never had a WC3 as I started with the WC4. People with the 3s were looked down on b/c that was "last year's" model and it looked so plain and pathetic compared to the 4s at that time ;-).
