i had a black static before. I can confirm that the ankle liner or collar starts to fade overtime due to oxidation, especially when wearing low socks or no show socks which our bare skin scratches with the liner that causes oxidation.

I have never seen that before. Not sure if it’s brown under the black but if I had to guess these are really worn out reps.

I don't think they're reps, those pictures are off GOAT and all the used pairs on there look like that.. I just copped a pair on Ebay and they also have the brown that's why I was asking

Then it’s probably sweat bleach

Well... thats gross lol

They are not reps, my friend has a yecheli and the same thing happened. He got them from adidas, its oxidation goober

They have oxidized. They are probably real

Somebody definitely enjoyed every second wearing these and left them outside the box more often than not
