help with ebay purchase for my son

[jordanmom]

My son wanted these retro 4 cab size 7 grade school really bad.  I won the auction on Ebay for $118.00 which is really cheap compared to the other auctions.  My 13 year old friends looked at the pictures and said they might be fake.  They said the tongue might be too big and the price is too low.  They are only 13 but think they know everything about sneakers.  The sneakers didn't arrive in the mail yet, but my son is afraid to wear them back to school because he thinks they might be fake.  Can someone please tell me if these are Authentic jordans.  Thank you so much!!!
