What is a "bootee"?

A bootee is a type of footwear that covers the feet and ankles like socks or slippers, but is thicker and designed to be worn as a shoe. bootees are typically made from soft materials such as fleece or wool and are often lined with a cozy fabric to keep the feet warm. Bootees are commonly used as a protective covering for infants, particularly for newborns who have not yet developed the ability to regulate their body temperature. They can also be worn by adults as a comfortable alternative to traditional shoes or slippers. Bootees may have a non-slip sole to prevent slipping on smooth surfaces and can be secured to the foot with elastic or other fastenings.
