Using these Wolky Nomad sandals is a breeze. Just adjust the three Velcro straps to get the perfect fit for your feet. You can wear them for casual outings during summer, like going to the beach or a picnic. When it comes to maintenance, it's best to keep them away from water as much as possible. If they get dirty, use a soft cloth to gently wipe them clean. Don't use harsh chemicals on the leather. Store them in a cool, dry place when not in use. Remember, the measurements might vary by size, so choose the one that suits you best based on the size guide.
