To use these shoes, simply lace them up and you're ready to hit the road for a great run. When running, you'll feel the support from the GuideRails® technology which helps you keep a natural stride. For maintenance, clean the shoes regularly with a soft brush and mild soap. Avoid using harsh chemicals as they might damage the materials. Let them air - dry naturally, don't put them in the dryer. Also, make sure to check the soles regularly for wear and tear. If you notice significant damage, it might be time to replace the shoes.
