Olukai's Kia'i Sandal for men is a water resistant, quick drying sandal that is the official sandal of the Hawaiian Lifeguard Association. It includes a jersey knit lining and neoprene foam backer for added protection, soft nylon toe post webbing, a non-slipping Eva footbed, and compression molded Eva midsole for support and stability. The Kia'i uses the deeper, anatomically contoured drop-in comfort to fit better and feel great.
