adidas took inspiration from their very first NMD R1 colorway with the NMD XR1 ‘OG’ sneaker. The sneaker features the original NMD R1s black upper as well as its blue and red EVA plugs. The difference between the NMD R1 ‘OG’ and this NMD XR1 ‘OG’ is the black TPU cage on the midfoot, as well as its Primeknit upper versus the original’s mesh upper. The NMD XR1 ‘OG’ hit stores on May 20, 2017.
