I don't know what to think of these shoes. I can buy these but I don't know if these are real or not. You see the white part underneath in the middle, I saw a lot of pictures of this model and normally it's black but in some video's on youtube it's white as well. I have no idea if this is a sign that it is fake or not... please help me out here. I know if you have doubts you should buy them in a official nike store but they were sold out in a minute. Now someone's offering them online in my city. I hope someone is so friendly to help me. Thank you in advance!
