What happens when you take proven Chaco technology like pull-through adjustable webbing straps and LUVSEAT PU footbed and marry it with modern design? It might look something like the Chaco Men's Z/Volv 2 Sandals. Featuring contemporary aesthetics, classic Chaco design features, and an airy PU compound that's softer underfoot and 20% lighter than Chaco Classic Z sandals, the Z/Volv 2 is the ultra-light sandal you've always wanted. Material: Polyester.
