Using these knee pads is easy. Just slip them on over your knees before you start pedaling. Make sure they fit snugly but not too tight to avoid discomfort. When you're done using them, take them off gently. For maintenance, it's a good idea to clean them regularly. You can use a mild soap and water to wipe them down. Let them air - dry completely before storing. Avoid exposing them to extreme heat or sharp objects as this may damage the protective insert and the fabric. Keep them in a cool, dry place to maintain their quality.
