I love turning a heel when I knit a top-down sock. This is a picture of the second Jazz Vanilla Socks just after I turned the heel and picked up the gusset stitches.
After I turned each heel of my first 5 or so pairs of socks, I paused and admired the amazing ability of turning a flat piece of knitting into a heel. Who thought of how to turn a heel? It didn't make sense to me. I simply followed the instructions each time with blind faith.
Still after 7 years of knitting socks I stop and gaze upon a correctly turned heel and smile.
