The Cavu 2 is a versatile running shoe with a bold and simple look. Similar to the Mach, it features PROFLY™ midsole, but the Cavu is a little lower and a little lighter. The PROFLY™ midsole is made with rubberized foam, which is light, responsive and durable, so you can run fast in the Cavu again and again. This shoe employs seamless, engineered mesh and upper and delivers a smooth, light ride. You are clear for takeoff.
