Adidas' monochromatic takes aren't going anywhere. Newly leaked catalog images show two pairs of upcoming Adidas NMDs in triple white and triple black, respectively.
The shoes make up a small "Japan Pack" drop, this one using Japanese branding on the midsole pieces that's been spotted elsewhere on Adidas NMD colorways. Note that there's already a black Japan pair out there, but the one shown below is much darker.
Based on the catalog images, both pairs appear to have Primeknit uppers.
As these leaks are showing up well before any sort of Adidas announcement around the shoes, there's no sneaker release date information available yet. Both pairs have been spotted before, with images surfacing back in February.
