These Keen men's sandals are perfect for both water and trail adventures. To put them on, simply use the quick - cinch bungee lacing to adjust the fit. They're easy to take off too. When using them in water, the Aquagrip rubber will give you good traction on wet surfaces. For long hikes, the arch - supported insole will keep your feet comfortable all day. After use, you can wash the polyester webbing upper to keep them clean. Just let them air dry due to the quick - dry lining. Keep them in a dry place when not in use. And don't worry about odors as the Eco Anti - Odor feature will take care of that naturally.
