The Chaco Mega Z Cloud Sandal layers Chaco Cloud cushioning into a dual-density polyurethane midsole for active comfort. The LUVSEAT footbed, certified by podiatrists, promotes arch support and healthy alignment. Wide polyester jacquard webbing straps wrap around the foot and through the midsole. What Our Gearhead® Experts Are Saying:“On wet docks and gravel paths, the lugged rubber outsole kept my footing steady. Once I set the ladder lock buckle, the straps held their fit through the whole afternoon.”
