Hi all, I found a pair of Nike shoes that I am wondering if they are authentic. They were issued from the fall of 2013 and number is 599537 888 82 LN2. They have O.J. Mayo's logo on the front of the tongue with #5. Tag on inside said it is a promo sample shoe. They are white with green bottom and heel and red swoosh. They look authentic but I don't think Mayo ever played with jersey #5. Any insights would be helpful. Thanks.
