Why kids need Barefoot Shoes?

It is estimated that 80% of foot problems are attributed to misshaped and inflexible shoes. Because of the high proportion of cartilage and other soft tissue, the developing foot can be deformed under the persistent pressure of wearing incorrectly shaped or rigid shoes. The child’s foot does not fully mature until age 18–19 for girls and 20–21 for boys and growing evidence supports that children’s shoes should be designed on the barefoot model.
