The Cavu 2 is a versatile running shoe with a bold and simple look. Similar to the Mach, it features a 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 a seamless, engineered mesh upper and delivers a smooth, light ride. You are clear for takeoff. Complete your comfort goals by adding insoles that are specifically designed for running, like the Superfeet RUN Comfort Thin Insoles and the Superfeet RUN Comfort Women's Insoles.
