I've finished my first Sidewinder sock. Here are some not-so-pretty pictures:
The toe is a little blocky but comfortable.
I like the vertical construction. I sort of thought the stripes would go straight up but they wobble over my instep. I have very high arches, and the sock is a little tight over the top. Normally I do my heels over about 60% of the stitches and that takes care of it. I can't quite figure out how to do the same thing here. At first I thought of doing fewer heel decreases/increases, but doing the same number of rows. But that would just change the bend, which I don't think is the issue. Short rows across the top of my ankle? It's not tight enough to make the sock uncomfortable, but it's noticeable.
Here are the decreases in the inside of my foot,
and here are the increases on the outside. They're much less noticeable. On the next sock I think I'll try to match up the increase (K in the row below) and decrease better. I might even follow Nona's suggestions; I was worried about them being too tight but it might look better.
I have enjoyed knitting this, although I'm not sure I'll make another pair. I think I like a more traditional construction better because you can adjust the fit as you go. It's a well written pattern for a nicely made sock, but I think Nona must be more adventurous than I am!
The jury is still out on the wool (Reynolds Swizzle). It seems kind of scratchy right now but we'll see how it wears.
