These Keen hiking shoes are easy to use. Just lace them up and you're ready to explore the outdoors. When wearing, make sure the laces are tight enough for the Konnectfit heel - capture system to work well and give you a secure feel. For cleaning, use a soft brush and mild soap to gently clean the surface of the shoes. Avoid using harsh chemicals as they may damage the KEEN.Dry waterproof membrane. After cleaning, let them air - dry naturally. Don't put them in a dryer as high heat can warp the shape of the shoes. When not in use, store them in a cool and dry place. Replace the removable PU footbed if it loses its support over time for continued comfort on your hikes.
