I remember hearing from a few different sources (one, I think, was the pediatrician) when my son was at that age that it's best to NOT have them wear shoes as much as possible - even when you go out (if you're going somewhere where she'll still be inside, on carpet, etc.) .... If I recall correctly, the reasoning was that having NO shoes helps them get the feel of balancing on their feet properly ... my son was virtually shoeless (he wore socks of course!) until he really started walking all the time - and now he's five and seems perfectly fine.
Here's what I found on the web: "Doctors recommend that babies learn to walk in their bare feet. Babies who learn to walk in their bare feet are more likely to have proper development in their feet." (from RefreshArticles.com)
From ParentCenter.com: "Until then, he'll just need some socks or booties to keep his tootsies warm when it's cold. In fact, even after your child's racing around, it's a good idea to let him go barefoot whenever it's safe. He'll enjoy the sensation of various surfaces (soft sand, lush carpet, cool tile) beneath his feet, and a barefoot base will him build strength and coordination in his legs and feet, too. For places where he'll need protection, though (outdoors or on a splintery surface, for example), get him a pair of comfy shoes that will aid his toddling efforts.
"With all this focus on feet, you may notice a few things that make you wonder. Keep in mind that a child's foot is still developing, and so it might not look — or act — like an adult foot. If your child still has a padding of baby fat under his arches, for example, he might appear a bit flat-footed. Or he may have a tendency to turn his toes in when he walks, called "in-toeing" or "toeing in" (which most kids outgrow by the time they reach school age). Be sure to mention any concerns at your next well-baby checkup, because foot problems are much easier to correct when your child is little. Other concerns to point out include a foot that rolls in at the ankle, or one foot that turns in more than the other."
Any shoes you do get for when she's out need to be very, very flexible - almost a soft fabric kind of sole - so she gets the feel of balancing.
Have fun!
