Nike is notorious for releasing specific models to be sold exclusively in parts of the world. The Nike SB Dunk Lows pictured above have been reported to be selling now in certain SB retailers in Mexico.
The mystery SB Dunk Low features a gradient front panel and the rest of the shoe composed of Red patent leather. Unfortunately, there is no official word that there will or will not be a Mexico exclusive series but stay posted for more info. Via Colmilludo.
