Ronnie Fieg’s story with Adidas began 2016 with the release of their collaborative Tubular Doom model in January, and it now ends with a duo of exciting new models, including an all-new silhouette.

Fieg worked closely with the Three Stripes over the course of a year to develop a completely new silhouette design – the UltraBOOST Mid. After multiple trips to Adidas’s headquarters in Herzogenaurach, Germany and extended communication, Fieg and Adidas were able to fabricate a completely original interpretation of the UltraBOOST. This heightened variation maintains the same performance sensibilities as its predecessor, but instead opts for a variety of detail modifications for a more luxurious approach. First, the collar features a ribbed sock-like appearance for a snug fit, while additional padding locks the wearer’s foot in place for a sturdy ride. Next, the upper is cage-less, instead opting for taped panels that create a subtle branding nod. Another first for Adidas is the all-over multicolored Primeknit upper, which utilizes a seasonal palette for the winter climate. The Primeknit is made from a wool-blend fabric for the winter, and is executed in a much denser knit than normal to retain warmth. Other details include added heel pulls for increased accessibility, matte white heel cups to complement the white BOOST™ midsole and tonal Continental outsole. Lastly, the laces are created from the same multicolored Primeknit to match the upper perfectly.

The second model focuses more on outdoor recreation functionality, as Fieg applies his unique taste to the Response Trail BOOST. This sneaker represents the evolution of the trail shoe, as it combines technical qualities with lifestyle insights. The upper features a double-layered mesh vamp and neoprene collar with premium tumbled nubuck overlays. Fieg applies asymmetrical Three Stripes logos to the speed-lace system, which offers fast and snug lacing. This performance-driven upper is mirrored by its sole unit, as the midsole is equipped with exposed BOOST technology at the heel and BOOST foam in the forefoot. Lastly, the Continental outsole lugs are inspired by Trail King bike tires to create extraordinary grip in all conditions.
