The running shoe you have, the item number is AMF72134, is a very popular running shoe from Hongxing Erke in 2007. We can’t replenish this style in our store now. . . As for authenticity, what I want to say is that there are very few fake Hongxing Erke shoes on the market, almost none. There is also an anti-counterfeiting label on the shoe box, just check it out.
