Query: Best Knee Pads I've Ever Used

I bought 2 pair of these knee pads for installing bamboo flooring. Having experience installing laminate flooring in the past, I knew how much time is spent on my knees. My son and I are renovating what was our guest room into his new bedroom so I bought a pair for him too. These pads are great! After several hours spent on my knees, I didn't have the soreness and stiffness that usually accompanies this type of task. I won't do another job without them. I had no problems adjusting the knee pads and they stayed in place pretty well.
