Before your baby starts walking, he or she doesn't need real, hard-soled shoes. Socks, booties, or soft-soled baby shoes can keep your baby's feet warm, and bare feet are fine, too.
But once your child takes those first momentous steps, it's time for real shoes with a supportive sole (probably rubber) and a more substantial upper. Shoes protect kids' feet outdoors and anywhere else that could be hazardous – on a splintery surface, for example. Get tips on buying your baby's first shoes.
Don't keep your new walker's shoes on all the time, though – letting your baby go barefoot (or just in socks) when it's safe is a good idea. Toddling around with bare feet actually helps kids build strength and coordination in their legs and feet.
