My feeling is that you should still stretch and move your legs on a long flight..even if wearing the support stockings. Even on short flights, I try to do leg lifts, knee pulls and such while sitting. I'm a "leg crosser" (doing it now at the computer!...like a lady!) so I try to keep them uncrossed on the flights.

It's a problem of non-diabetics as well. I mean, not a diabetic problem. But some clots have formed that have been deadly a short time after flights.
