This is the only knee pad with REAL Memory Foam. The advanced memory foam cushioning containts something they call a patented dual layer progressive resistance padding. The two foam layers are over 1 inch thick.I have used other knee pads before, and this is hands down my favorite. I even bought the expesive Pro-Knee pads and that doesn't even come close to the padding in the Total Comfort knee pads.The website says they are the first and only doctor recommended knee pads and have special approval for Total Knee Replacement patients, so they must be good. They have a page with the research and lab testing on their foam too, so you can actually see how the foam is better.I got to test out a pair of these before they even hit the market. I can honestly say they are way better than anything else you'll find, and they are at a fraction of the cost from ones like pro knees.Here's their website:
