There are few reasons why your feet could turn out, and some are fixable. Try this test: Stand up when barefoot and wearing shorts (or no pants) and line your feet up so they're parallel. Then see if your kneecaps are aligned with your feet, or if they're turned inward, like the picture on the right: i.imgur.com/llpvt.jpg
You may need to have someone check you from the front (or take a picture of yourself.)
