'Behold our lightest, most responsive Mach to date. This lively trainer has been fine-tuned for extra energy return with a super critical foam midsole and updated for enhanced durability with strategic rubber coverage in the outsole. Implementing speed focused design details throughout, we’ve enlisted a new creel jacquard upper with zonal breathability and an internal gusset to deliver the foot-hugging comfort required to set your next PR.'
