How to use: Just lace up these shoes and you're ready to hit the road for your daily runs. They're great for everyday use, whether you're jogging around the neighborhood or training for a race. Note: The 6 mm drop is approximate because of the manufacturing process. Make sure to choose the right size according to your foot measurements. Maintenance: To keep your shoes in good condition, clean them regularly with a soft brush and mild soap. Let them air - dry away from direct heat. Avoid getting them too wet if you're using them in extreme weather, as the synthetic materials may take longer to dry.
