It can be purchased through the primary market, such as physical stores, official website, and available apps (available apps were officially authorized by Nike on 16).
It can also be purchased through the secondary market, such as poison app and nice app. The purchase process of these two platforms is delivered to the platform through the seller. The platform has a professional appraiser, who will send it to the buyer after passing the appraisal. Authentic products are guaranteed by the platform. At present, many sports shoes are purchased on two platforms. Don't talk to me about Tian Miao and the treasure. Without genuine guarantee, you are talking nonsense and can't defend your rights at all.
I hope I can help you!
