Mach has the award-winning Clayton in its genes, which boasts the same startling trio of benefits: maximal cushion and responsiveness in a surprisingly lightweight package. Mach takes lightweight performance to a new level with a dual-density PROFLY midsole and a full Rubberized foam outsole. PROFLY provides a forgiving landing and responsive toe-off while the Rubberized foam outsole offers additional responsiveness as well as durability. Mach stands out further from the pack with its lightweight and open engineered mesh upper, which offers both a comfortable fit and optimal breathability.
