These Eric Michael Isabella booties are super easy to use. Just unzip the dual zippers, slip your feet in, and zip them up. You can wear them with different outfits like jeans or printed dresses for various occasions. When it comes to care, keep them away from sharp objects to avoid scratches on the leather. Wipe them clean with a soft, dry cloth regularly. If they get wet, let them dry naturally at room temperature, not near a heater. Also, remember that the measurements provided are for size EU 38 (US Women's 7.5 - 8), width M (B), and they may vary with different sizes.
