adidas' recent infatuation with glow-in-the-dark detailing -- seen most recently in the Yeezy Boost 750 "Light Grey" -- continues with this upcoming Ultra Boost colorway. This time around, it's the Primeknit upper, and not the sole unit, that gets the luminescent treatment, which otherwise appears in a subtle grey and bright green color combo in natural light. Black interiors and a white Boost midsole complete the look. Stay tuned for word on a release date.
