Am I out of luck?

I went to foot locker, and their was no line and that is when a person who worked their told the 5 of us who were their waiting they were only doing raffles. And they're not selling any pairs unless you won the raffle. So i rushed home added money to my paypal account and spammed click on infrared 6's for champs and house of hoops. They were all sold out in all the sizes so I went to nike.com and they only had a size 17 and 18 in stock. I kept on clicking both of them until I got one of them in my cart and it was the 18. I bought it with no hesitation... and note I am a size 9.5.

Long story short is their any way I can trade this in with one of those stores that sell them early for my size or sell it for flight club price then buy it from their. What would you do if you ended up with a pair of size 18 infrared 6's when your size 9.5? Because I really don't know what to do. Also I get them next friday on December 5.
