Saw these socks on the website of a big box sports store and they got great reviews. On a whim, went on the Reebok site, and not only were they significantly less, but had free shipping. These socks are very comfortable, and even work with larger calves. They don't feel too tight or cut off circulation in your feet on runs. Wore them for trail runs and a race, and they felt great! If you're thinking of trying out compression socks, these should be the first ones you get.
