Refined for SS21, Hoka’s Challenger ATR 6 continues to impress. An all-terrain running shoe known for its versatility, it performs light on the trail and smooth on the street. The cushioned CMEVA foam midsole absorbs impact and provides support. Zonal 4mm lugs on the sole offer optimal grip while reducing weight. Constructed with sustainability in mind, the mesh uppers use Unifi REPREVE recycled yarns. Made from post-consumer plastic waste, it helps keep plastic bottles out of landfill.
