The adidas Ultra Boost officially went to the mid-cut heights, with Ronnie Fieg’s “Aspen” collaboration introducing the revised silhouette to the masses. This version you see here is the adidas Ultra Boost ATR Mid Primeknit, which features a higher ankle collar and the Ultra Boost 3.0 Primeknit ribbing on the upper. ATR, which signifies All-Terrain, suggests that the shoes are built for outdoor use, which is additionally made evident by the bulkier rubber outsole. A release date hasn’t been confirmed just yet, but expect the Ultra Boost ATR Mid PK to release early in 2017.
