Designed to Slide anything Mother Nature Outer its way, Hoka One One® M Speedgoat 4 Atlantis Dazzling Blue’s black Challenger Low GTX is waterproof and beefed-up for the trails. It’s made from a combination of nubuck and GORE-TEX and has the brand’s signature Meta-Rocker 25th in the sole. A hit of reflective 3M at the heel and a lugged rubber sole complete the go-anywhere style.
