No shoes for as long as possible. They tend to also find them more difficult to walk and navigate ups and downs etc in them.

When you do get shoes though start with the soft, you'll find they only go up to certain sizes though, then change to hard. So once they grow out of them you don't really have a choice. If possible its best to spend a little extra money and get shoes fitted for them. It makes a huge difference.

DD2 has the tinest feet ever, she is 2 1/2 and barely in a size 5, some even won't fit her and she needs a 4. She has hips issues though and my gp recommended a fitted pair of shoes with high supports to help turn her feet out, as her hip rotation make her tend to turn in.
