Using these Keen Kaci slip - on shoes is super easy. Just slip them on your feet and you're ready to go. Whether you're going to the garden, running to town, or going to work, they'll be your great companion. For maintenance, you can wipe them clean with a damp cloth regularly. When it comes to odor control, thanks to the Cleansport NXT™ technology, it will keep them fresh naturally. But try to avoid soaking them in water for a long time as it may damage the material. Also, don't use harsh chemicals to clean them. If you notice the elastic gore panel loses its elasticity over time, it might be time to consider getting a new pair.
