I honestly did not know this! My feet always point outwards on walking, I thought everyone's did! (Caveat, I have lupus, so always odd things going on with tendons, ligaments and joints).
I saw my physiotherapist today, and we are working on foot flexibility following an ankle break. I had a stroke 2 years ago and my right side is always weak, so foot flexibility in that side is always poor but following the break, it's nearly non-existent.
So we were walking on that, and she said as I stood my feet were pointing out, right more than left. I have bursitis x3 in right hip, same side as break, so hip isn't clever. Anyway, we soon established that I walk with my feet out too, and that isn't normal!
Currently doing exercises to gradually retrain, and being everything back in to alignment it feels so much lighter to walk when feet are all the way forward, I feel like I've just gained a superpower!
Odd the things you never consider are abnormal because it's the way you've always done them.
Just wanted to share this really. It sends such a stupid thing not to know, but when your body's always wonky there's no normal to compare it with.
