Using these On Running Cloud 5 shoes is easy. Just lace them up using the speed lacing system or the classic laces that come with them. You can wear them all day, whether you're traveling or going about your daily routine. For best results, avoid wearing them in extremely muddy or dirty conditions as it might damage the breathable mesh upper. When it comes to maintenance, gently wipe the shoes with a damp cloth. You can also use a mild detergent if there are stubborn stains. Let them air - dry naturally, away from direct heat sources. Don't machine - wash or dry them, as this could affect the structure and performance of the shoes.
