Women's Keen Outdoor Hyperport H2 Sandals The KEEN Hyperport H2 is a women's outdoor sandal built for warm-weather wear and active days around water. This closed-toe style combines an open-sided upper with a quick-cinch closure for an easy fit, while the extra-thick injected foam midsole is designed to keep the shoe light and cushioned. Aquagrip rubber pods on the outsole are intended to add traction on wet surfaces.
