Footwear for snow can include boots, which is a four-letter word that is often used to describe this type of footwear. Boots are typically made of waterproof material and have a thick sole to provide insulation from the cold and wet conditions of snow. They also usually have a higher shaft to protect the wearer's ankles and calves from the cold. Boots are a popular choice for winter activities such as skiing, snowboarding, and snowshoeing.
