This razor sharp offering from adidas mixes futuristic tech with retro inspired aesthetics for a fresh new outcome. The Retropy P9 get their inspiration from two decades of iconic running heritage. The lightweight textile upper, suede overlays and chunky outsole are a throwback to the '80s, and the high-performance silhouette is straight out of the '00s. A cushy Boost midsole provides all-day comfort from heel to toe.
