These Keen hiking shoes are great for various activities like working out and hiking. To use them, simply put them on like you would any other shoe. They're designed to fit comfortably right out of the box. When it comes to cleaning, use a soft brush and mild soap to gently clean the mesh upper and rubber outsole. Avoid using harsh chemicals as they might damage the materials. For long - term storage, keep them in a cool, dry place. If the insole gets dirty, you can remove it and wash it separately. Also, make sure to dry the shoes thoroughly after getting them wet to prevent mold and odor. With proper care, these shoes will serve you well for a long time.
