Winter resort rentals often include skis, which is a four-letter word. Skis are a type of equipment used for skiing, which is a popular winter sport. Skiing is a recreational activity that involves sliding down a snow-covered slope while standing on two long, thin pieces of equipment called skis. Skis are typically made of wood, metal, or plastic and are attached to the feet with bindings. Skiing is a great way to enjoy the winter season and can be done at many winter resorts. Renting skis is a great way to enjoy skiing without having to purchase them.
