I have rheumatoid arthritis and struggle working ten plus hour shifts. It is not only my knees but all my joints that bother me. Especially my hands but these help a lot with me standing and walking all day. I would highly recommend them. Almost feel like I do not have the arthritis and it helps me walk without limping or have my knees buckle on me. The thing I really like about them is the fact they are not bulky. I can where them under my pants. They are easy to get on and off. I have been wearing for a little more than a year now and they are still holding up as if though they were new. I tend to wash them every couple weeks unless it is the summer than they get washed more frequently but they have not lost any tension or anything yet. Was considering of purchasing another set incase the price goes up and these ever begin to show any signs of wear
