We addressed this question somewhat above, but the short answer is maybe. They do seem to help in some cases but in others show little effect. Manufactures such as CEP, Skins, and 2XU all have scientific studies cited on their websites. Take a look by clicking on the name of the brand. Conversely, compression tights are not without criticism. Our common sense tells us that while these tights are not a magic cure for everything, they do offer a bit of an edge, and trying never hurt anyone.
