The adidas ZX 500 RM combines a 70s track aesthetic and contemporary materials. Updated in October 2018, this Core Black edition works a dual-patterned mesh and nubuck upper, supportive TPU heel clip and leather heel badge. A D-ring lacing system and serrated Three-Stripes give the sneaker its retro authenticity. The Boost midsole and rubber outsole are deployed underfoot to absorb shock and improve durability.
