I'm really pleased with these, they're on my feet as I type.
I used a basic sock pattern, a 5 row repeat, with an afterthought heel. The afterthought heel is over more than half of the stitches, which I think makes it fit much better than it would have on only half.
I'm sure the same principle would work on a short row heel, as it's about the angle - I read an article in (I think) Interweave.
