That's the difference,they should already have a strong yellowing characteristics being that they naturally yellow over time.Especually being that they are from a 2009 release.The only way your sole looks so icy is simply because it was recently made in a factory that distributes replicas.Trust me,the exact sane ting happened to me.Which is why I'm asking you to do what I was suggested to do and got my money back.I don't know your situation,but I got ripped off and lied to on ebay of course.Abd was told to me that they were b grades.So overall,if you need help just come back here.As I said don't know how you got them or when.
Last thing,starting to yellow and already being yellow is two totally diff things.Hope this helps you.Good Luck !
