High end knee braces. Pretty much the same ones on fortnine for $900. These are an older model with only difference being how they are put on. It takes a bit to get them dialed in for your legs but once you do they just take a minute to put on. They are a large but they fit smaller. I would say average or smaller legs. I bought them on Used Victoria a few months ago and as much as I wanted them to fit they are too small. Just trying to get what I paid, very high quality braces.
