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. Heel Drop: 5mm. Weight: 7.2oz.
