I would suggest you use an easier pattern for a first time attempt. This sock seems, on the surface haven't dug deep into the pattern, to be complicated. I consider myself to be a fairly sufficient knitter and I wouldn't even attempt it. I wonder about those seams. I think they would rub against your skin and the inside of the shoe and be very uncomfortable. This isn't standard sock construction. You may want to get some experience with a few pair of socks with traditional patterns before you do something a bit off the wall like that pattern.
Compare that pattern to this simple basic sock pattern and see the smooth lines. Socks have smooth lines for comfort when you're going to be wearing them all day long.
