How to use: Just lace up these boots tightly using the quick - adjust lacing system before heading out on your hike. They are suitable for various terrains and weather conditions between - 20°F and 50°F. Notice: Don't use these boots for extreme mountaineering activities not within their temperature rating. Avoid contact with sharp objects that could damage the leather or nylon upper. Maintenance: After each use, clean the boots with a damp cloth to remove dirt and debris. Let them dry naturally in a well - ventilated area. If the leather looks dry, you can apply a leather conditioner to keep it supple.
