Using these boots is easy. Just open the double - strap Velcro, put your child's foot in, and fasten the straps. Make sure to adjust them for a secure fit. When it's snowy, use the nylon locking snow collar to keep snow out. For temperature regulation, the boots work well on their own with the double aluminum insole. Regarding maintenance, after use in wet conditions, let the boots dry naturally in a well - ventilated area. Avoid direct sunlight or heat sources as they may damage the materials. You can gently clean the boots with a damp cloth. If the inner boot system gets dirty, you can remove it and clean it according to the care instructions. Remember, these boots are designed for cold - weather use, so don't use them in extremely hot conditions.
