Although the adidas NMD range is getting a lot of attention these days, don't let that fool you into thinking the brand is done with the Ultra Boost. In fact, from the looks of things, it's only getting started.

Previewed here is an unreleased Ultra Boost sample that sports a white Primeknit upper and is broken up with a purple heel cup. The Primeknit pattern itself is the updated gradient variation, while the outsole is strengthened with a white Continental rubber.

It remains to be seen if this pair will make it to retailers, but we'll let you know as soon as we hear something official. In the meantime, you can shop the current Ultra Boost colorways right here for $180 each.
