I need to get one for my son for Christmas. they are sold out every where. found some on http://www.jdsneakerkicks.com/air-j...-2016-mens-shoe-black-dark-concord-white.html and http://www.jordanspacejam11.us.com/. Just wanted to know if any of you guys bought from these sites before. I hate buying them and ending up with knock offs.
