The Hoka One One Mach 4 takes a technological leap forward inspired by the Carbon X and the Rocket X and constitutes a significant update. Unlike the Carbon X and the Rocket X, the Mach 4 does not contain a plate. It does, however, use Hoka’s new PROFLY midsole foam which results in a lively ride. Combined with an early stage Meta-Rocker, this midsole will allow you to cover a wide variety of distances at any speed. The upper has also been updated with heat-pressed TPU embroidered yarns for great security and lockdown, an engineered mesh upper for flexibility and breathability, and a “Swallow Tail” heel configuration to remove pressure from your achilles. This is a light and responsive everyday trainer that you need to try out at Fleet Feet Albany.
