Although cosmicpluto promises that this is a holeless heel, it isn't, at least not in my version. But that's ok. I didn't mind mending the hole in the corner. With God as my witness, I will never knit a flap heel again.
This sock and heel seems to fit so much better than the flap heeled one. The proof will be in the wearing though. My one fear is a heel that works its way down under the foot as you wear it. If it does that, I will have to change my vow. But for now, I am hurrying to make the second sock so that I can test them out. After that, my next sock will be toe up.
