Our Take 

The new Mach 6 is a lightweight trainer that can handle some mileage but really comes to life for shorter, faster runs and would be equally comfortable on the start line of your next race.  Although there is no plate imbedded in the midsole like the Mach X, the Mach 6 is the lightest, most responsive Mach to date.  This fast-paced trainer has been fine-tuned for extra energy return with a new super critical foam midsole that feels much more soft and lively than the firmer feeling Mach 5.  The new creel jacquard upper with zonal breathability is also must more foot-hugging than the previous version.  And with more durability to the outsole you simply get more out of a great shoe.
