Roller skiing is a type of endurance sport that simulates cross-country skiing on dry land using specialized skis with wheels. It combines the techniques of traditional skiing with the mechanics of rollerblading, allowing athletes to train year-round regardless of snow conditions. Roller skis come in different types, including classic (straight) and skate styles, depending on the technique used. The sport is popular among cross-country skiers for maintaining fitness, improving technique, and enhancing strength and balance. Roller skiing can be practiced on paved surfaces such as roads and paths and is often performed in groups or races. It requires specific safety gear, including a helmet and protective pads, due to the risks associated with speed and falls.
