Adidas is fully aware of how coveted the various "Triple White" Ultra Boosts have been, and will continue to milk the style with this similar release. The shoe isn't all white, and uses some grey sections that flash under the proper light.
This white reflective version of the Ultra Boost leaked before, with images arriving back in May that showed off even more reflective touches on the Boost cushioning on bottom.
Adidas has used reflective Primeknit before on the adidas Ultra Boost on colorways like this.
