Big name brands like Nike, Adidas, Puma, etc. are continuously striving to stop the selling and importing of fakes and because of this, they only sell through authorized distributors. You may contact them directly and request for their list of authorized distributors or enquire how you can be one. That said, you would need to register with them.
Hope that helps! Let me know if you have other questions or concerns!
