The structure of the foot is primarily soft cartilage, usually not strong enough to support the body
Learning to stand
Cartilage rapidly develops into bone
Early weight-bearing years where the legs and feet go through several stages of development
The bowed legs and “toed-in” feet of infancy straighten out as the child begins to walk.
