Our lightest model of the Z/Sandal yet, Chaco Z/Volv sandals are made with the performance and fit you need for an active outdoor lifestyle. Our Z/Volv sport sandals are 20% lighter than our classic Z/Sandals. The Z/Volv model comes with an extra-airy LUVSEAT™ PU midsole with textured grooves for added traction, as well as our iconic, adjustable webbings for a custom fit. Plus, the outsole is made with EcoTread™ 25%-recycled rubber compound, so both you and your feet can feel good about these athletic sandals.
