Using these boots is easy. Just lace them up using the traditional lacing system and you're ready to go for winter activities or hunting. When it comes to cleaning, use a soft brush and mild soap to clean the PU - coated leather upper. Don't use harsh chemicals as they may damage the coating. For the faux fur lining, you can gently vacuum it to remove dust. Store the boots in a cool, dry place. Avoid leaving them in direct sunlight or a damp environment as this can affect the materials and the waterproof membrane. Remember, these boots are designed for extreme cold, so use them in winter conditions to get the best performance.
