Almost as fun as doing a cannonball into a placid lake Nike's Sunray Adjust II sandals offer a fashionable fit that kids can call their own. Along the top is a stretchy and fast-drying Lycra® Spandex synthetic upper with a Velcro closure for easy adjustments. This fast-drying design is excellent for playing around the pool or shoreline. The footbed has a ridged profile that facilitates fast-draining between the foot and the sandal but you won't find any contoured arch--this is a play shoe intended for recreational wear. The sole features a non-marking solid rubber compound that helps keep the streaks off your kitchen floor.
