Spring 2013 is proving to be a great time for sneakerheads. From Jordan’s to Air Max, Nike is providing kicks with great colorways for the warmer seasons. The Nike Air OG “Ultramarine” is a very simple, clean shoe with a smaller air unit than the original. The vintage midsole look is also different than the original, and adds a clean but worn in feel. The Ultramarines are set for a release sometime in March at select retailers.
