What kind of shoes can my 12-month-old wear?

Several points. Babies feet develop well when barefoot. If they are going into an area where their feet need protection, you follow basic needs:1.Sturdy enough for the terrain, 2. Flexible to cradle & move with the feet 3.A proper fit to avoid calluses or confining the foot 4. A material that will breathe enough for the skin to remain healthy.
Choices. You can either wear a hard soled shoe such as by stride rite or a soft shoe.
Flexible sole. Shoes protect your child's feet, but are not necessary when your child is learning to walk inside. When your child finally needs shoes, choose shoes with a flexible sole.
