While the current hype is all about adidas’ recently dropped NMD’s, the sportswear giant’s Ultra Boost silhouette remains coveted by many, especially with the "Triple White" and "Triple Black" on recent blog rotation. However a new and unique interpretation of the runners has appeared shrouded in mystery as to what or where it came from. With no official information seemingly available save for a branded "S.E.P." on the tongue’s label and lace ends, all we have are either well-photographed leaks or a very well done home-made rendition. However from the images we can deduce that the Primeknit upper has received a cool grey (or possibly white) outer knit around the toe-box and possibly leather cage, while black adorns the mid, top and tongue. The heel counter and Boost mid-sole comes in white, topped with a black outersole. Most interestingly is the inner sock lining, which gets what we think is a color-blocked design, as well as a criss-cross slash patterning, which can also be found on the sneaker’s laces. Let us know if you find any more information about this curious iteration of the adidas Ultra Boost in the comments section below, or look out for more information from us to come.
