These shoes come ready to wear. Simply lace them up securely to achieve a snug, comfortable fit, ensuring your foot doesn't slide inside the shoe, especially on descents. The Merrell Agility Peak 5 shoes are designed for trail running and hiking; they are compatible with varied natural surfaces including dirt, rock, mud, and uneven terrain. They are not specifically designed for road running, which can prematurely wear down the aggressive outsole lugs. For care, after each use, remove any visible dirt or mud. Allow them to air dry naturally at room temperature, away from direct heat sources like radiators, which can damage materials. Avoid machine washing; instead, gently brush off dried mud and wipe with a damp cloth if necessary. Periodically check the laces for wear and ensure the insole is clean to prevent odors. Proper care will extend the life and performance of your shoes.
