There are a few ways that you can make your knee pads tighter so that they stay in place and provide you with the support and protection that you need. One way is to simply adjust the straps that are attached to the pads. If the straps are too loose, then tighten them until they are snug but not too tight. You should also make sure that the knee pads themselves fit well. They should be snug against your skin without being too tight or too loose. Another way to keep your knee pads in place is to wear socks over them. This will help to create a barrier between your skin and the pad itself, which will prevent slipping and sliding. Finally, if you find that your knee pads still aren't staying put, you can try using bandages or tape to secure them in place. Just wrap the bandages or tape around your leg, above and below the knee pad, making sure it's tight but not too tight. With a little bit of adjusting, you should be able to get your knee pads to fit just right!
