The Chaco Kids' Z/1 Sandal is a strap on sandal for kids on the go. The Z/1 webbing is durable and secures tiny feet to the Footbed; so they can tromp through mud, rocky rivers, and the playground. The Luvseat Footbed supports their arch with a diamond pattern on the surface to prevent slipping. The EcoTread rubber has 25% recycled content and 2mm lugs that won't mark up your kitchen floor. When the summer dirt has been caked onto the webbing, toss them in the washer for a fresh start.
