The adidas Ultra Boost goes back into collaboration mode on this new release, created by Germany's Solebox.

The shoe is part of the adidas Consortium World Tour, a series that has top-tier adidas accounts across the globe outfitting silhouettes new and old with their touch.

This is the second collaboration to go the Uncaged route on this sneaker, although this pair manages to set itself apart via the use of suede on the back and a tonal grey colorway. Solebox branding appears on the tongue tab and heel while a special insole confirms its place in the Consortium collection.

Solebox is having a pre-release on March 12 at its stores at 11:00 CET and online at a random time the same day. There's no word yet on an international release.
