The adidas Ultra Boost is growing up. Soon enough, the model will get its height extended by mid versions, the likes of which have been previewed by Ronnie Fieg via his Kithland fashion show. Shown here is another leak of a purported future Ultra Boost release.

The model is supposedly called the adidas Ultra Boost ATR Street. The "ATR" designation has been used for the original Ultra Boost recently, with pairs using those three letters to denote "All Terrain." This shoe doesn't have the same waterproof coating, although perhaps it's the more rugged-looking outsole here that results in the ATR status.

There is no sneaker release date information yet regarding when and where this Ultra Boost will be available.
