A great deal of my time working is spent on my knees (no crude comments, please), whether it be indoors or outdoors. I got a set of kneepads for the first time a few years ago, as I noticed them gaining popularity among workmen of all trades. The first pair I got were comfortabe, and had hard plastic knee caps. Well, the first time I squatted down on a smooth troweled concrete floor in them, my one knee slipped out sideways due to the hard plastic cap. Plicture doing a "split" on your knees. I pulled a groin muscle or something, because I sure was sore for a while. After that instance, I threw the pads out with the hard plastic caps and got a $3 pair that are just all foam rubber with a velcro strap. That's pretty much what I've been using ever since, but I've gone through several pairs. They don't last too long (maybe a year), but they are only 3 to 5 bucks a pair. I'm about due to shop for a new pair, and I thought I'd ask for recommendations. It seems like there must be a pair by now that are considered "the best" by a lot of people. They need to be non marking, for kneeling on finished flooring from time to time. Help me out.
