Using these On Cloudswift 3 shoes is a breeze. Just slip your feet in, and you're ready to hit the road for a run. Whether you're running in the city or on hard surfaces, these shoes will offer great support and cushioning. When it comes to maintenance, it's a good idea to clean them regularly. You can use a soft brush and mild soap to gently clean the upper part. Avoid using harsh chemicals as they might damage the material. Also, let the shoes air - dry naturally instead of using a dryer. When not in use, store them in a cool and dry place. Keep in mind that although these shoes are designed for a wide range of foot shapes, if you have very specific foot conditions, it's always a good idea to consult a professional.
