I love my Newzill Calf Sleeves. I bought the small/medium in white/gray and am 5 foot 2 inches. They fit perfectly, so much so that I bought another pair the same size, but in the black/purple color. I like them both, but the black/purple seems a little longer. They aren't a problem, but don't fit as perfectly as the white/gray. The sleeve material seems a little different as well between the two. It's hard to explain, but the black/purple pair seems a little thicker and rougher, more like sock material, than the white/gray pair which feels sleeker. I've had them about 2 months now, and they look and feel the same as the day I received them. I'm very happy with them and plan to buy more. I recommended them to a friend who also bought a pair. She liked them as well.
