The adidas Ultra Boost has had the most success staying away from the colorful end of the spectrum, with white and tonal grey pairs being among the most coveted.

The latest in a recent string of grey-based ones this this pair, which has been dubbed the "Mystery Grey" by followers of the shoe. That doesn't appear to be the official color though – the shoe's official listing on the adidas site calls it just "solid grey," while some on social media are calling it "iron grey."

Pairs have already disappeared at a handful of retailers here in the U.S., but this adidas Ultra Boost is available now directly from adidas.
