Adidas expands their collection of the recently-introduced Tubular Doom silhouette ($160) with the release of this Grey Primeknit colorway. This time, the popular runner receives an all-grey Primeknit construction on the upper with a reflective 3M underlay offering a distinct look when under direct light. The heather grey upper is contrasted by an off-white Tubular outsole and grey striped 3M rope laces. White Adidas branding can be seen at the ankle collar as well as embossed on the heel counter for a finished look. Purchase your pair online and in-store now.
