How to use: Simply slip on these sandals and you're ready to go, whether it's a hike, a trip, or a stroll around town. Notice: Although the sandals have good traction on wet surfaces, be extra careful on very slippery areas. Maintenance: You can machine wash these sandals to keep them clean. Make sure to air - dry them thoroughly before using them again. Also, if you find the odor control feature not as effective after a long time of use, you can try using some natural deodorizers like baking soda inside the sandals.
