To use these shoes, simply lace them up tightly but not too tight to restrict blood circulation. They're great for high - speed running on roads. When you're running, you'll notice the fast feel and smooth transitions. As for maintenance, it's a good idea to clean them regularly. Use a soft brush and mild soap to gently scrub away dirt. After cleaning, let them air - dry naturally. Avoid putting them in the dryer as the high heat can damage the materials. When not in use, store them in a cool, dry place. Also, keep in mind that these shoes are designed for road running, so don't use them on rough or uneven terrains that could cause excessive wear and tear.
