All the sneakers I offer are 100% authentic and sourced from a Nike authorized dealer such as Footlocker, Footaction, Champs, or Nike Factory Stores or smaller local chains. These sneakers are often marked up at a premium since they are usually limited editions, retros or specialty shoes whose inherent value increases after their day of release. These sneakers are often sold out at any of the retailers mentioned above. Consider this premium a convenience fee you pay for securing your pair from a reliable source and without the headaches of having to line up for hours or camp out. All sales of these products are final.
