What happens when you take proven Chaco technology – like pull-through adjustable double straps and our luvseat pu footbed – and marry it with modern design it might look something like the z/volv X2. Featuring contemporary aesthetics, classic Chaco design features, and an airy pu compound that’s softer underfoot and 20 percent lighter than our classic z sandals, the z/volv X2 is the ultra-light sandal you’ve always wanted.
