These sneakers are super easy to use. Just untie the laces, slip your feet in, and tie them up to a comfortable tightness. For a casual look, you can pair them with jeans or shorts. When going out at night, they'll go great with a nice pair of chinos. As for care, wipe them clean with a damp cloth regularly to keep them looking fresh. Avoid machine - washing as it may damage the patchwork pattern. Also, don't leave them in direct sunlight for too long as it could fade the blue color. If they get wet, let them air - dry naturally. When it comes to sizing, always measure your feet carefully as described in the size guide to ensure a perfect fit.
