Remember some companies, not all, bootleg from the Nike factories. So when Nike places an order for, lets say, 800,000. They might actually make 950,000 pairs and bootleg 150,000 pairs because Nike is only paying $1/pair. They can make a lot of money doing this and some companies do this. They would be the closest thing to authentic as you can get! But ALL are fake coming out of China unless you buy from a Nike approved dealer (even if it comes out of the Nike factory...) or buy from a liquidator that bought from the Nike approved dealer.
