Since Cara asked nicely, I’m going to try and document my process of kniting the Jaywalker socks toe-up.
I’m not going to detail the Queen Kahuna toe-up heel method, but all of you who are toe-up knitters probably have a favorite toe-up heel of your own that you’re partial to, so just substitute it when you get there.
To begin with, I want to show off my beautiful yarn:

Not only does it look good in the hank, it’s even prettier wound up in a ball, which is nice, since plenty of hand-dyed yarns lose their charm when they’re wound and you really see all the colors together.
Anyway, So I’m using my very favorite needles (that are sadly discontinued) Inox Express size 0 circulars. I think they discontinued their 0’s, 1’s and 2’s. I’ve been wanting to stock up, but it seems like almost nowhere still has them in stock.
I don’t remember which episode it was, or I would link to it, but I recently saw an episode of Kintty Gritty where they did a provisional cast on where they looped the yarn around the cable of a circular needle so the stitches would already be there when you went back to knit the other way, and you wouldn’t have to pick them up. There are instructions for something like this in Queen Kahuna’s book, but her instructions didn’t make sense to me, so I played it by ear. I did a long tail cast on where I ran the tail end under the spare cable after every stitch. I think the stitches are twisted funny, but they lay totally flat, so there won’t be an uncomfortable seam.
I cast on 32 stitches, and am doing a normal double-wrapped short row toe, working down to 12 stitches and back up. This will make a fairly shallow toe, but it works well for my feet. Here’s what the provisional cast on looks like, and my toe-in-progress:

Once the toes are complete, and the provisional cast on has been picked up, you’ll be all ready to knit the foot (you will need to pick up a stitch at one of the sides, since the other side of a provisional cast on always has one less stitch). To set up for the pattern rows, you will need to first knit the following 4 rows:
Row 1: Knit plain all around.
Row 2: Knit plain on sole side, k-f/b, knit 30, k-f/b on instep side
Row 3: Knit plain all around
Row 4: Knit plain on sole side, (k-f/b, knit 15, k-f/b) twice on instep side
You will now have 32 stitches on the sole side needle, and 38 on the instep needle. Begin knitting in pattern as written in the original pattern only on the instep needle.
I promise to post pictures when I have enough on the needles to show what the pattern looks like upsidedown.
