Using these shoes is a breeze. Just slip them on, and you're ready to hit the road for your city runs. For the best performance, make sure your feet are clean and dry before putting them on. When it comes to maintenance, it's a good idea to wipe off any dirt or debris after each run. You can use a soft, damp cloth to gently clean the upper part of the shoes. Avoid using harsh chemicals as they might damage the zonal knit material or the 3D heel padding. Also, store them in a cool, dry place away from direct sunlight to prevent the colors from fading. And remember, these shoes are designed for running on hard surfaces like concrete, so try not to use them for activities on very rough or uneven terrain to ensure their longevity.
