This year, Nike has gifted us a bunch of Air Force 1 sneakers with unique designs, from 40th anniversary editions to celeb collabs, proving the versatility of the Bruce Kilgore-designed classic.

For the newest iteration of the AF1, Nike has dressed a pair of Air Force 1 High in full tonal greys. Smooth grey leather covers the upper, while hits of suede in a slightly warmer grey hue are spotted on the lace cage and Nike-branded heel. A metallic silver Swoosh adorns the side, adding some needed shine to the shoe.

However, the real star of this pair of Nike air Force 1 High is found underneath—on its translucent outsole. When flipped upside down, a large Swoosh in Nike’s signature Volt shade is revealed across the outsole, making this the only (non-grey) color to be found in the entire shoe. It is this attention to detail that adds to this pair’s precious quality.

The official name and release date have not been confirmed, but we are going ahead and calling it the Nike Air Force 1 High “Hidden Volt Swoosh”. Follow along for more release detail updates!
