You expect a little more from your sandals than just a thin barrier of rubber between feet and the ground. Keen ups the ante with the Women's Rose Sandal, a feminine fit sandal not afraid of trekking through a little water. A washable synthetic and polyester upper straps in your feet with a webbing system designed to disperse even pressure over the entire foot, rather than pinch certain areas. An adjustable hook-and-loop strap further customizes the Rose's fit by securing the heel. Both the mesh upper lining and the EVA footbed have been coated with an Aegis anti-odor shield to block odors by eliminating the bacteria which cause them. For incomparable support, Keen crafted the EVA footbed with an internal, metatomical system; in layman's terms, this means an anatomical arch engineered to cradle the natural contours of the foot, especially the arch.
