I'm a huge fan of them for recovery, and my drugstore Futuro brand work just fine.

I really like the CW-X tights for longer runs, too, but KiwiStoker is right that the research on compression during activity is equivocal. CW-X incorporates a design that's supposed to be like kinesio taping, so maybe it's that rather than the compression that helps me. Or maybe it's just placebo effect.
