Crib shoes and baby booties are the exact same thing—the only difference is what you prefer to call them. Baby girl booties are a soft, slipper-like foot covering that slides on in the same way as a sock. Though babies tend to prefer being barefoot, these supple foot coverings are an essential dressing item for newborns and infants. They keep the chill off your baby feet when you take her out in her strollers or when she's crawling outdoors on a cool day.
