The HOKA Mach 6 represents the biggest transformation in the series to date! Reworked from the ground up this shoe is lighter, faster and more durable - a great option for a responsive tempo shoe. The heart of this refresh to the Mach lineup is the introduction of a supercritical foam midsole fine-tuned for a high energy return and plush comfort. This single layer of foam offers versatility for both uptempo runs and daily miles.
