I second the CW-X capris. I have a pair that I wear when it's kind of cold. I LOVE the support. They are not cheap, but they are nice. I have 2 pairs.

I don't know anything about the other two. If you have, uh, shall we say, shapely calves like I do, then the "gripper" around the calf will matter to you. That's my one complaint about the CW-X...a little too tight (but not unbearable). I have some Adidas running capris that I also love. They have a little slit at the bottom so I don't get any calf constriction. They are made for those of us with bigger legs.

CW-X seems to run small-ish. The Adidas ones are true to size.
