Are my Jordan Retro 13 Flints fake?

Well for some reason everybody keeps saying my Jordans are fake, i mean the only way it looks fake is the way the tounge is styled and i just got mines for $80.... My boyfriend has almost all the Jordans out there and he said that if i could see 4 fingers on Jordan on the tounges, and if you see the tounges sticking out on the shoes on that little icon thing and if you pick up this thing in the shoe and you see the stitching then its real.. My homeboy also got almost all the Jordans out there and he took a really close look at them and he said the same exact thing as my boyfriend did.. Oh and my friend said that if i type in the cereal # in google thats on the inside of my shoes and it comes out to Flints then its real.. So im confused, i need help please -___- thanks
