How to use: Just lace up these shoes and you're ready to hit the road or trail for your run. Whether you're a casual jogger or a serious runner, they'll support you every step of the way. Notice: Make sure the laces are not too tight or too loose to avoid discomfort. When running on rough terrain, be careful as sharp objects could potentially damage the shoes. Maintenance: After each run, wipe off any dirt or mud with a damp cloth. Let them air - dry naturally, away from direct heat sources. If they get really dirty, you can use a mild soap and water solution to clean them gently, but don't machine - wash or dry them as it may damage the waterproof membrane and the structure of the shoes.
