While Adidas is still using colored Boost cushioning pretty sparingly, the brand has been slowly extending that treatment to more and more models. Usually it does so with soles matching the rest of the shoe, as with this latest "Triple Black" design.
The silhouette here is the Adidas NMD XR1, a model updated with the R2 Primeknit pattern that recently debuted on the NMD runner. This shoe already saw a triple black release via this XR1 style from September.
Note that for now this looks to be just a sample, and a retail release of the "Triple Black" Adidas NMD XR1 model shown has not been confirmed by Adidas.
