In order to inhibit (turn off) the left AIC pattern, a right foot has to pronate. If it doesn't pronate, your right sided musculature won't “let go“ and allow your right glute to push you to the left. If you can't get to the left, you can't get left AF/IR to establish left stance. You'll never get your left frontal plane. You'll never get out of your anterior pelvic tilt. You'll never get out of lumbar extension. I could go on and on. Simply put, the right foot has to pronate out of a supinated position. This sequence of events must happen with every step you take, otherwise you are walking with compensation.
