They will not let your leg hyperextend or twist and like anything else you will get use to wearing them. They felt a little funny when I first wore them! But, after my first wreck which the quad landed right on top of my legs. I knew that I had the right braces. I was able to stand right up after a bad accident with the quad. Also they are very light weight and once you get used to them you can walk run or do anything else for that matter. Thery are a little bulky, but it doesn't hender you from riding!! :)
EDIT:The Cell asterisk knee braces without a doubt, is the most advanced-designed knee brace I have ever seen. It has an orthopedic background and comes with a custom fit device through the riders own simple adjustment. If you need superior protection for your knees, then I suggest you get these braces. They come in 5 sizes which is SM,MED,LG,XL,XXL. To ensure a proper fit, they take the circumference measurements of your leg to make sure you have a comfortable fit! :D
I would recomend these knee braces to everyone. diffently a must when riding..

They also come with a sleeve for your leg so the braces don't pinch your skin!!
