I have tennis elbow but my supports weren't doing as much as I needed them to, especially at work. How great to get an email from Comrad about the new compression sleeves! I wear their compression socks to work & my feet no longer hurt at the end of the day. I ordered size M sleeves based on the measurements chart. I have arthritis in my hands, and the sleeves were somewhat difficult to get on. Once on, they were difficult to adjust. But, unlike my old supports, they didn't slide, twist, or shift no matter what I was doing. They didn't bunch up or feel scratchy. They weren't hot or too thick under my clothes. I would likely go up one size to L next time I order, however. I like them.
