These are brand new with tags. The brand is wave zone the style is Kai. These are a kids size 13.  To me they appear to be girls but could work for a boy too. These are gray with aqua accents. They are sandals. They have one velcro strap and are close toed. The material of these shoes would dry fast if they get wet so they would work great for water shoes. Make sure to look at the pictures!
