I'm well into the second New Pathways sock, and my sizing qualms are mostly assuaged. The first one fits well enough as long as I don't just pull it on; it takes a few seconds of patting to make it fit, but once that's done it's OK. I think it could do with 4 or 6 fewer stitches to be slightly tighter, because loose socks are bad, but it's certainly not unwearable if only as a house sock.
That said, this book is about five times more complex than it really needs to be. Newbie knitters are not going to be buying the thing, so I'm not sure why everything has to be so damn complicated--I mean, Bordhi's invented new abbreviations for things like picking up wrapped stitches when doing short rows, and writes them out when she could quite easily just say, "Knit across, picking up all wrapped stitches". There's just in general a whole lot more writing things out than there needs to be, and it makes the patterns intimidating, with huge long paragraphs that look terribly scary until you realize they boil down to "put stitch markers surrounding center 4 stitches of sole" or whatever. Come to that, I'm pretty sure most of the patterns could have been condensed into one, with a description of where to put the increase point to get the different effects. Also I am unclear why the toes and heels went in the back in an appendix rather than having their own chapter at the very beginning with all the other techniques.
Don't get me wrong, it's a cool book and I'm pleased with it, but some of the design choices puzzle me.
