Stand with your feet directly under your hip bones and your toes forward.
Look at the arches of your feet and the inside of your ankles. Are they dropping toward the midline? What is the shape of your foot?
If your arches are dropped, externally rotate your thighbones to help lift the arches of your feet. Your inner ankles should move in and away from the midline as well.
Spread your toes long.
Do your feet look like kidney beans?
