I currently use these knee pads.


These are really easy on the knees, which is a good thing, but I find that they don't really stay put, and that the ridged, knife-edge plastic bearing surface tends to cause the pad to roll to one side, creating instability at awkward times and just plain annoying. And once the pad moves over and starts bearing on one of the hard plastic edges, it's a lost cause, and placing weight on that pad often causes it to rock severely, which is uncomfortable and unsafe; the pads are a couple inches thick, so there's quite a bit of opportunity for movement.
Because of this, I find that I use the pads less than I should, and when I do use them I'm forever repositioning the pads so that they stay directly beneath the knee, and not semi-rolled over to one side. This is irritating in the middle of some operation when I need to shift my knee or move around.
I bought these because they were supposed to be one of the best, but they leave something to be desired in my book, despite their excellent comfort when they're adjusted just perfectly. The real problem is how apt they are to move around during normal use.
Does anyone use a set of kneepads that they really like, and would recommend?
