I'm thinking of getting them also ...I do have arthritis from working with my hands all my working life...I'm not sure about the bare finger tips though...?
I have been using the Tommy Copper knee sock [For years now]....And every now and then i'll blow out my left knee and when that happens i'll ware it for a week and the knee is like new again...I don't know how or why it works just compression maybe?? Don't see any copper in them...But its better than surgery....
