Jordan 11 Concord Legit Check Thanks

Hi

I just got a size 9.5 once used Jordan 11 Concord from someone I know that he got from a reseller.

Production date says
7/13/2011 - 10/06/2011
on both shoes

Box has no stamp

Looks good on everything except

What is questioning me:

(weird but the carbon fibers doesnt seem the same on the shoes - are these normal)
1 looks a little different than the other, but when beamed to the sunlight, they look the same

and the sole doesn't seem to have some yellowing yet

Thank you guys, please help me legit check these if the official release and not early ones.

any help please?

If there's no yellowing what's over then they're prolly unauthorized.

They look real, but the no yellowing probably means they are a pair from Taobao. (China's eBay)

Thank you. Coming from Taobao does that mean they are legit or not? Are all from taobao those?
