However, they should be bought large enough so they cannot in any way constrict the feet or toes. When the baby begins to toddle about on the cool floor, these booties or soft slippers, which yield to the pressure of the baby's toe movements, are the most suitable. Infants' feet do not have to be protected from the cold nearly as much as some adults think. Babies need no more protection for their feet when crawling on a cold floor than they do for their hands. The reason most adults are concerned about exposing their babies' feet is because they are used to having their own feet always covered and protected, and are not accustomed to a little bit of exposure.
Babies actually thrive on it.
When your child begins to wear socks, you must take the same care in fitting them as with shoes. A sock is not made in the shape of the foot. It is made more like a tube that tapers to a point at the end of the foot. For this reason stretch socks can be particularly harmful they cause constant pressure on the toes. If a sock is pulled tight over the child's toes, his toes will tend to take the shape of the pointed sock.
