That is the name of this sock pattern: Riding the Metro. These photos don't show the lace detail very well, but the front has an arrow-like design, while the back looks like tracks.
Pattern: Riding the Metro by Wendy Johnson (from Socks from the Toe Up)
Yarn: Shelridge Farm Soft Touch Heather in Charcoal
Last year I knit quite a few pairs of socks using the Yarn Harlot's "sock recipe" in order to learn to knit socks without a pattern. Those socks were knit from the top down. This year I am concentrating on learning to knit socks from the toe up. The advantage is, if you run short of yarn, you can make the tops shorter. I think they fit a bit better, too. These I did on two circular needles. The first sock took forever, but the second one was quicker. Even so, the next pair will NOT be a 24-row lace pattern - too much work!
