The Lowdown is Chaco's most lightweight pair of sandals. But lightweight doesn't mean they've lost all that Chaco charm. They've still got the signature Z-Strap, with fully customizable adjustment at the top and heel. They've still got a high-rebound EVA footbed with Chaco's beloved arch support. And they've still got a non-marking rubber outsole with a grippy 3mm lug depth.
