To use these Merrell Moab Flight trail running shoes, simply put them on like you would any other pair of shoes. Tie the 100% recycled laces to a comfortable tightness. These shoes are great for running on trails, but you can also wear them for other outdoor activities. When it comes to maintenance, remove the removable PU foam insole regularly and let it air dry. Use a soft brush to clean the 70% recycled mesh upper gently. Avoid using harsh chemicals as they might damage the materials. Store the shoes in a cool, dry place when not in use. Keep in mind that while they are durable, extreme conditions might affect their performance, so use them within reasonable limits.
