These men's high - top sneakers are a great addition to your wardrobe. To wear them, simply untie the laces, slip your feet in, and tie the laces to your desired tightness. When it comes to sizing, remember to check the size chart as different suppliers may have variations. For instance, if you're used to a US size S, an Asian size L might be a better fit. As for maintenance, these breathable sneakers with split leather uppers and PU linings can be kept clean by wiping them gently with a soft, damp cloth. Avoid using harsh chemicals as they can damage the materials. And always store them in a cool, dry place when not in use to keep them in good condition.
