My quick and easy scoop a purl means that the stitches on my sock ribbing would be twisted if I knit like most people. So I purl through the back loops. And I like it. Most people don't like that move, but for me a double or even a triple just is not a problem. Well maybe a triple is work, but the move is so easy and natural that the back loop purl rounds are slightly faster that the knit rounds.
Just one of the things I love when I knit socks.
And here they are, ready for heels.
