Take a good look at the next step in NMD silhouettes because, for the now, that's all you're getting! The adidas NMD has only been walking this earth for a few months now but the iterations of the shoe are fast becoming legion. The NMD spawned into the NMD_R1 and subsequently into a chukka boot adaption, and now there's an all-new shoe, the City Sock PK, which seems to be a raise of the NMD_R1's profile. The NMD Runner Chukka comes in both black and red suede, and the City Sock PK – the real star of this update – is made from flexible Primeknit. Both have 'The Brand With The Three Stripes' spelled out on the heel tab in varying languages, while the City Sock has 'S79152' printed on its medial side. Is that a model number? A new name? Will these be limited enough to be numbered? We'll keep you posted as soon as we know.
