First I used the magic loop technique which I often use for two at a time socks.
Then, specific to that pattern:
Knit it twice up to the increase mini-gusset section.
Then you can either keep track of left vs. right socks very carefully or put one sock on a spare needle to hold it until you have completed through the decrease mini-gusset section.
There was some sticky moving stitches around to make it work, but I think its worth it to not have to knit them one at a time.
I put the heal stitches on safety pins until I finished knitting the rest of the socks and then I Kitchener stitched it together, but when you do it isn't a big deal.
Then the legs are the same again, but pay attention to which way they are facing.
Happy Knitting :)
