The HOKA Mafate Speed ?? 2 shoes were built to offer support and cushioning in technical terrain at any distance. This update includes an active foot frame for support and a tuned Meta-Rocker to facilitate smooth transitions through the gait cycle. The outsole uses deep bending grooves to adapt to a variety of terrain, and the 5mm Vibram Mega-Grip outsole adapts to even the toughest surfaces.
