Hey guys, I've been lurking this forum for quite some time and I know there are countless threads regarding knee pads. I have a patellar subluxation (my kneecap doesn't slide within the groove), and the last thing I'm looking to do is injure my knees on a fall. I have narrowed it down to POC VPD 2.0 and Troy Lee Designs KG 5450. I get pain when my knees are in something real tight/constricted so I'm looking for a pad that adheres to my leg but isn't too restricting. I read one review regarding POC VPD and the individual stated that if someone has knee problems that they should stay away from that product. Any suggestions would be appreciated. Does anyone have similar issues?
