I'm thinking that the feet are one thing and maybe there's more to it. From what I understand, the body tends to compensate and tries to self-adjust for "weakness" on one area.

Several events: college cross country coach sent me to a podiatrist and I got the custom orthotics made of hard plastic with no give.

Then years later a orthopedic guy, famous for working on the L.A. Lakers, he showed me how my flat feet and knock knees will limit my long term sport of distance running.

Then twenty years later, the pro bike fitter asked me to walk up and down the hallway. That right leg is turning inwards, and a history of an injury.

Now in 2018, the Yoga guy says I'm way out of alignment and to get out of that "compensatory" status, go for stretching and posture correction. So now stretching and holding the pose.
