That's good info from Liza Jane. The wider your base of support, the more stable you are, so it can be good to walk with wide legs if your balance is bad, like she said. Also, when you turn your feet out, it makes your knees more stable, so this helps people who have some weakness or even sensory loss in their knees. You can "pretty up" your gait if you use a walker, because then the walker provides you with the extra stability. But most people don't want to fool with one unless they have to.
