Using these running shoes is easy. Just slip your feet in, and you're ready to hit the city streets for a run. For best results, make sure your feet are clean and dry before putting them on. When running, you'll notice the great cushioning that helps reduce the impact on your feet. As for maintenance, after each run, wipe off any dirt or mud with a damp cloth. Let them air - dry naturally; avoid using a dryer as it might damage the materials. If the shoes get really dirty, you can gently hand - wash them in cold water with a mild detergent. Also, store them in a cool, dry place when not in use. These shoes are made for running on hard surfaces like concrete, so try to avoid wearing them in extremely wet or muddy conditions for a long time to keep them in good shape.
