The well-received Adidas Ultra Boost 4.0 isn't due out for a few more months, but new colorways continue to surface.

This time, it's the "Core Black" variation, a staple look within the series. As usual, the runner sits atop full-length Boost cushioning and black Continental rubber.

There's no confirmed release date for the striped motif at the moment, but we'll continue to keep you posted as the Ultra Boost 3.0 era comes to an end.
