The adidas Ultra Boost is back again, this time releasing in a colorway dubbed the "Core Black 2.0" that's got a black upper with a tonal Primeknit treatment.

Black pairs of Ultra Boosts haven't been as quick to disappear lately as the white ones, but those wanting to add these to their rotation might want to act fast given how much energy there is around this silhouette right now.

Readers can buy this adidas Ultra Boost style now here.

This pair is also releasing later this week at Eastbay.
