What's going on with the return of the Nike Air Tech Challenge 4 in this beloved original colorway? The shoe appears to have already released in Europe, but has yet to touch down at stateside retailers. Suggesting that it's coming soon though is this set of official product images from Nike.

The sneaker is not totally true to the original Air Tech Challenge 4–this version features the updated NikeCourt logo on the insole that's been a staple of Nike tennis retros as of late.

The good news is that Agassi retros have steadily been going on sale lately, so those wanting to purchase a pair of these Air Tech Challenge 4s probably won't have a hard time doing so when they do hit U.S. stores.
