I also wear Sockwell compression socks at work and for flights - they do make a difference without being uncomfortable. I have the medium compression, and I bought them from Amazon (they have plain black if you want them for work). I was a little worried about the brand when I first bought them, since they're not one of the "top names" that athletes etc use, but they are pretty comfortable at a reasonable price, they wash/dry well, and they are holding up to wear and laundry. And, FWIW, I am overweight with big calves, and they still fit without being uncomfortable
