Nordic skis are a type of ski designed for cross-country skiing and ski touring. They are typically longer and narrower than alpine skis, allowing for efficient gliding over flat or gently rolling terrain. The bindings on Nordic skis usually allow for the heel to lift, enabling a natural striding motion. These skis are often made from lightweight materials like wood or composite materials, which enhance performance and maneuverability. Nordic skiing is a popular winter sport that can be enjoyed in various environments, from groomed trails to backcountry areas, making it accessible for skiers of all skill levels.
