Just need some help. I picked up a pair of Thor Force knee braces. I like them but they rub the back of my leg raw. I think its from the velcro. I also notice that they are wearing out my pants and wearing the plastics on the bike. I picked up a Thor knee brace pads that are to go over the side so it does not wear your pants but can't figure out how to put them on. Any tips on getting these things to work better. They offer good protection, just need to be fine tunes. Thanks.
