To honor the Hawaiian Lifeguard Association (HLA) and the brave women and men that protect the shores, OluKai took one of their favorite sandals, the Punua, and emblazoned the HLA mark on it. Water-resistant synthetic straps. Welded HLA strap logo. Soft nylon toe post. Quick-drying jersey knit lining. Anatomical poured PU footbed with micro-texture for traction and a lower profile for a modern, clean look and feel. Non-marking Wet Grip Rubber outsole with a color design inspired by ocean depths and molded siping for enhanced traction on wet surfaces.
