There's more than one way to knit a sock and lately I've been fascinated by gusset heels. They have a turn heel section and a gusset section, like a more traditional flap and gusset heel, but there's no heel flap and no picked up stitches.
Gusset heels can be worked from either the top down or from the toe up. When they're worked from the toe up, they are sometimes known as a Fleegle heel.
