Using these New Balance running shoes is easy. Just lace them up to your desired tightness using the adjustable lace closure. They are great for all kinds of running, whether it's a casual jog or a more intense training session. When it comes to maintenance, you can gently wipe the shoes with a damp cloth to keep them clean. Avoid using harsh chemicals as they may damage the synthetic/mesh material. Store them in a cool, dry place when not in use. Remember, the 6mm drop is approximate, so don't be too worried about small differences in the actual drop.
