There's no shaping in these, but I have chicken legs. lol.
I did decrese 4 stitches total along my ankle and then increased again right before my calf...so, I guess that's some sort of shaping. Really, I just kept trying them on as I went along to see how they fit. I also knit about 1 1/2 inches of k1p1 ribbing to make sure that they'll stay up.
I'm in love with toe-up socks now....it seems like you have so much more control over the size and shape of the sock when you can just try it on as you go...and, no worrying about running out of yarn!
I used Wendy Johnson's pattern found here.
I'm glad to hear that the yarn gets softer...I'll have to run them through the wash a few times, then.
