Using these Keen hiking boots is easy. Just lace them up using the speed - lace webbing system for a snug fit. They're great for all types of outdoor hikes, whether it's a muddy path or a rocky trail. When it comes to maintenance, you can use a soft brush to clean off dirt after each use. Let them air dry naturally, and avoid direct sunlight or heat sources as this can damage the materials. To keep them odor - free, take out the removable PU insole regularly and let it air. Also, check the TPU overlays and reinforcements from time to time for any signs of wear. With proper care, these boots will serve you well on many adventures.
