To use these boots, simply put them on like you would any other boots. Make sure to zip them up securely. When it comes to sizing, they are true to size, so you don't have to worry about getting the wrong fit. For maintenance, use a soft cloth to wipe off any dirt or dust. Avoid getting them wet as much as possible. If they do get wet, let them dry naturally away from direct heat. These boots are a great addition to your wardrobe and can be worn for various occasions, like parties or a night out.
