How to use: Simply lace up these boots like you would with any other hiker - style shoes. They're great for walking on icy paths, winter hikes, or any outdoor winter activities. Notice: The Vibram® Arctic Grip color indicator will turn blue when the temperature drops below 32°F/0°C, so you know the grip is in its prime state. Also, avoid wearing these boots in extremely hot conditions as it may affect the insulation. Maintenance: After use, clean the boots with a damp cloth to remove dirt and debris. Let them air - dry naturally. If the leather looks dry, you can apply a leather conditioner to keep it in good shape. Make sure to store them in a cool, dry place when not in use.
