Japanese fashion brand Kolor is no stranger to the adidas Ultra Boost, and it looks like the brand has an Uncaged version in the works, too.
These images depict a Kolor x adidas Ultra Boost Uncaged sample. Unlike many of the more subdued Ultra Boost Uncaged colorways we've seen so far, this collaboration breaks out a colorful—no pun intended—Primeknit blend of light orange and blue.
Additional details include grey hits at the heel cup, ankle, and laces, while a blue Continental outsole caps off the full-length Boost.
Unfortunately, there's no telling whether or not this pair will make it out of its sample stage, but it's dated May 2016, so there's still plenty of time for a release.
