Excellent for paddling and rafting the Nike Aqua Sock IX has a stretchy textile upper that gives you a better fit than many water sandals that simply lock you into Velcro® strap sandals. The extra coverage along the upper is also excellent in windy conditions where cool breezes might leave sandaled feet feeling a little cramped in the cold. Along the bottom you'll find Nike's proven Nike All-Trac amphibious sole a versatile compound that keeps you in balance on wet and dry terrain.
