Funny you joke about that, though. I just pulled out a DS pair of the navy snakes the other day and thought to myself, whoa, these sure are a lot brighter than the pair I've worn at various times during the past 2+ years LOL. I'm still not ready to retire the worn pair and swap it out for a DS one, though.
One other thing I noticed on my two DS pairs of navys: The outsole has started to get a bit of that old yellowing around the pods, like on the 2011-era XI retros. It's the only "modern" XI model I have that is doing this. My DS Concords and SJs show no sign of it. Makes me wonder what's different on the navy snakes.
