Cement, concrete, elephant… call it what you will but the affection it invokes are all the same. Just minutes ago, the Cement/Elephant Skin design option on Nike iD is finally available. Select from either Air Force 1 High iD and Air Force 1 Low iD, with the opportunity to appoint the iconic pattern as its upper. Furthermore, as NIKEiD hinted earlier, two additional colorways are also available. Aspiring sneaker designers and Air Force 1 aficionados can now select the original Neutral Grey/Dark Grey scheme plus Midnight Navy/Neutral Grey and Varsity Red/Neutral Grey. As with all limited design options, Nike iD will only permit 750 pairs of Air Force 1s. So act fast and purchase your design now.
