Lol@that guy thinking we don't know our sizes just because a shoe doesn't fit our foot right. Everyone has a different foot, and every shoe in the world is not catered to be a perfect fit for everyone. I've tried 3 sizes in the Lebron X and none of them fit right. 11 and 11.5 are too tight, and 12 is a little too loose. I could have bought either 11.5 or 12 and lived with it, but I'd rather not shell out $200 for something that doesn't fit right for ME.
I have shoes by brands outside of Jordan/Nike, and I have shoes that range from 10 to 12. Every shoe is different, dude.
