They are okay..
I used them for a shooting platform on my elbows on concrete.
They did the job but I again expected a little more padding.
I had read other reviews on these and wasn't sure how they would hold up with the mud and dirt, but they were awesome.
A bit longer than necessary (I'm using my for indoor volleyball), and they don't breathe that well, but definitely no worse than other pads I've worn.
Outside of the pad ripped the first time it was used.
Contacted the manufacturer about a replacement, was told I would receive one, and months later still haven't.
Traditional knee pads just don't stay in place.
These are wonderful, they have just enough padding and do not need to be adjusted all day long.
Been wearing them for months and no problems.Update: After about 4 months use, the padding went flat.
