I bought 3 types of knee sleeves and love them all, they are doing their jobs perfectly! 2 are for running, I have a bad knee with a partially torn ACL, and the neoprene one is for work- I'm a farrier! I use it to protect my knees and it takes all the swelling down at the same time. I'm really impressed. All the sleeves stay in place, on top of my slippery leggings.
