Product details:

The first Mach boasted the HOKA trio of benefits: Maximum cushioning and super responsiveness in a surprisingly lightweight package. The Mach 2 goes a step further with its PROFLY midsole. That's a PORFLY midole made with rubberized foam, which makes for an even lighter and more resilient ride. It also uses and engineered, breathable mesh upper atop the responsive, stable package. This shoe is as fast as lightning and ready to race.
