To use these sneakers, simply untie the laces, slip your feet in, and tie the laces to your desired tightness. When you're out and about, these shoes will keep your feet comfortable thanks to the EVA insoles. They're great for walking around festivals or hanging out with friends. As for care, if they get dirty, use a damp cloth to gently wipe the leather upper. Don't use harsh chemicals as they might damage the leather. Since they're waterproof, you can wear them in light rain, but try to dry them thoroughly afterwards to prevent any unpleasant odors. And always remember to check the size guide before buying to ensure a perfect fit.
